Preparatory Stage
Grades 3 - 5 • 25 questions • 25 marksQuick answer grid
Detailed key with explanations
Q1The pictograph shows the number of modaks made on four days. On which day were the most modaks made?
DThursday
Thursday has 8 modak pictures, which is more than Monday (4), Tuesday (6) and Wednesday (3).
Q2The bar graph shows the number of eco-friendly idols made in four colonies. How many more idols were made in Colony B than in Colony C?
B20
Colony B made 35 idols and Colony C made 15 idols. 35 - 15 = 20.
Q3Look at the tray in the picture. The modaks are arranged in 4 equal rows. How many modaks are there in all?
C24
There are 4 rows with 6 modaks in each row. 4 x 6 = 24.
Q4Meena buys the 5 modaks shown in the picture at the price on the tag. How much money does she pay in all?
ARs. 40
Each modak costs Rs. 8, so 5 modaks cost 5 x 8 = Rs. 40.
Q5The evening puja begins at the time shown on the clock. At what time does the puja begin?
B6:30
The hour hand is just past 6 and the minute hand points to 6, which means 30 minutes.
Q6A clay idol is placed next to a centimetre scale, as shown in the picture. What is the height of the idol?
C12 cm
The base of the idol is at 0 and its top reaches the 12 cm mark.
Q7Look at the flowers in the picture. What fraction of the flowers are yellow?
D3/4
Three of the four flowers are yellow, so the fraction is 3/4.
Q8Look at the festival toran in the picture. How many triangles are used in it?
B5
Count the triangular flags on the string — there are five.
Q9The dotted line in the picture divides the rangoli into two halves that match each other exactly. What is such a line called?
CA line of symmetry
A shape has a line of symmetry when both halves match exactly on folding along that line.
Q10Four idols made of four different materials are shown. Which idol will dissolve most easily in water?
AIdol A, made of clay
Clay mixes with water and settles down, so a clay idol dissolves easily.
Q11The picture shows plaster-of-Paris idols left in a river even after many days. Why is this harmful to the river?
BThe idols do not dissolve and their paints pollute the water
Plaster hardens instead of dissolving, and the chemical paints harm the fish and plants.
Q12Many cities now build artificial immersion tanks like the one in the picture. Why do they do this?
CTo keep lakes and rivers clean
The idols are immersed in the tank, and the water and clay are cleared away later.
Q13Look at the four pictures of the celebration. Which one shows the step that is done at the end of the festival?
BPicture B
The festival ends with visarjan, when the idol is immersed in water.
Q14The mandap platform in the picture is 3 m long and 2 m wide. What is its perimeter?
D10 m
Perimeter = 3 + 2 + 3 + 2 = 10 m.
Q15The table shows the number of days for which four cities celebrate the festival. Which city celebrates for the longest time?
AMumbai
Mumbai celebrates for 10 days, which is more than Kolkata (7), Hyderabad (5) and Chennai (3).
Q16Durva grass is offered to Lord Ganesha in bunches, and each bunch has 21 blades. How many blades are there in the 3 bunches shown?
B63
Each bunch has 21 blades, so 3 bunches have 3 x 21 = 63 blades.
Q17Look at the number of diyas in each row of the picture. How many diyas should be placed in the next row?
C10
The rows go 2, 4, 6, 8 — each row has 2 diyas more than the row above, so the next row has 10.
Q18Lord Ganesha is also called Ekadanta. Look at the picture. What does the name 'Ekadanta' tell us?
AHe has only one tusk
'Eka' means one and 'danta' means tusk — the other tusk is broken, as seen in the picture.
Q19The three things shown in the picture are cooked together to make a festival sweet. Which sweet is it?
DModak
The rice flour makes the cover, and the coconut and jaggery make the sweet filling inside.
Q20Look at the four decoration materials in the picture. Which one is the most eco-friendly?
ACloth and leaves
Cloth can be used again and leaves rot away safely, while plastic and thermocol stay in the soil for years.
Q21What is the best thing to do with the used flowers and leaves after the puja, as shown in the picture?
DPut them into a compost bin
Flowers and leaves rot and turn into manure that is useful for plants.
Q22Look at the picture of the immersion place. Which is the safest way for a child to take part in the immersion?
CGo with an elder and stay behind the railing
The railing keeps children away from deep water, and an elder can help if there is a crowd.
Q23The festival begins on the circled date in the calendar and goes on for 11 days. On which day of the week does the 11th day fall?
BThursday
Day 1 is Monday, so day 8 is again Monday, and day 11 falls on Thursday.

Middle Stage
Grades 6 - 8 • 25 questions • 25 marksQuick answer grid
Detailed key with explanations
Q1The pie chart shows the waste collected in a colony after the festival. Which type of waste forms the largest share?
BFlowers and leaves
They make up 40% of the waste, which is more than plastic (25%), others (20%) and cloth (15%).
Q2The double bar graph shows the number of clay idols and plaster idols made in a town. In which year were the clay idols more than double the plaster idols?
C2026
In 2026 there were 260 clay idols and 100 plaster idols, and 260 is more than 2 x 100 = 200.
Q3The line graph shows the dissolved oxygen in a lake over four weeks, with the immersions held in week 3. In which week was the dissolved oxygen the lowest?
CWeek 3
The graph falls to 4.0 mg/L in week 3, which is the lowest point on the line.
Q4The table shows the turbidity and pH of four water samples taken from an immersion site. Which sample shows the greatest pollution?
DSample D
It has by far the highest turbidity (48 NTU) and its pH of 8.9 is the furthest from neutral.
Q5A colony made 250 idols in all, and 60% of them were clay idols. How many clay idols were made?
A150
60% of 250 = (60/100) x 250 = 150 clay idols.
Q6Modaks are made by mixing rice flour and jaggery in the ratio shown in the table. If 600 g of rice flour is used, how much jaggery is needed?
A400 g
3 parts = 600 g, so 1 part = 200 g and 2 parts of jaggery = 400 g.
Q7A model of an idol is made to the scale shown in the picture. If the model is 9 cm tall, what is the height of the actual idol?
D1.8 m
A scale of 1 : 20 means the actual height is 9 x 20 = 180 cm = 1.8 m.
Q8A circular immersion tank has the radius shown in the picture. What is the length of the fence needed to go once around the tank?
B44 m
Circumference = 2 x (22/7) x 7 = 44 m.
Q9The table shows the number of idols immersed in a tank on five days. What is the mean number of idols immersed per day?
C18
Total = 12 + 18 + 15 + 20 + 25 = 90, and 90 divided by 5 days = 18.
Q10The bar graph shows the festival waste collected in a city in two years. By what percentage did the waste fall from 2025 to 2026?
A25%
The fall is 200 - 150 = 50 tonnes, and (50/200) x 100 = 25%.
Q11A procession covers the distance shown in the picture in 4 hours. What is its average speed?
B1.5 km/h
Speed = distance / time = 6 km / 4 h = 1.5 km/h.
Q12Two ways of connecting decoration lamps are shown. In which circuit will the other lamps keep glowing if one lamp fuses?
ACircuit A
In circuit A the lamps are in parallel, so each lamp has its own path and one fused lamp does not break the others' circuits. Circuit B is a series circuit, in which one fused lamp breaks the single path.
Q13The graph shows the sound levels measured during a procession, along with the safe limit. By how many decibels does the dhol cross the safe limit?
C25 dB
The dhol measures 110 dB and the safe limit is 85 dB, so 110 - 85 = 25 dB.
Q14A ramp is used to move a heavy idol onto a truck, as shown. Why is the ramp helpful?
DIt reduces the effort needed to raise the idol
An inclined plane is a simple machine: the load is raised over a longer distance, so a smaller effort is enough.
Q15Four kinds of festival waste are shown above the two bins. Which one must go into the non-biodegradable bin?
CC - plaster piece
Flowers, leaves and coconut shells are broken down by micro-organisms, but hardened plaster is not.
Q16The picture shows what happens when plaster of Paris is mixed with water. Which statement explains why plaster idols harm water bodies?
BThe plaster sets into a hard solid that does not dissolve and settles on the bed
The hardened pieces block sunlight and the paints on them release harmful chemicals.
Q17In a school, 40 students made clay idols and 25 students planted saplings, as shown in the Venn diagram. How many students took part in at least one of the two activities?
D55
40 + 25 = 65 counts the 10 common students twice, so 65 - 10 = 55 students took part in at least one activity.
Q18Look at the rangoli in the picture. What is its order of rotational symmetry?
B4
The design fits on itself after every quarter turn, so it comes back to the same look 4 times in one full turn.
Q19A clay lump and a plaster lump were kept in water for 24 hours, with the result shown. What does this experiment show?
AClay breaks up and settles in water, while hardened plaster stays as a solid lump
This is why clay idols are far better for lakes and rivers.
Q20The timeline shows the year in which the festival was first organised as a large public celebration. How many years will be completed in 2026?
C133
2026 - 1893 = 133 years.
Q21A procession starts at the point marked on the street map and moves 3 blocks east, 2 blocks north, 3 blocks west and 2 blocks south. Where does it finish?
DAt the starting point itself
The 3 blocks east are cancelled by the 3 blocks west, and the 2 blocks north by the 2 blocks south.
Q22Chemicals from idol paints mix into a lake, as shown in the diagram. How do these chemicals finally reach people?
BThrough the food chain, as algae are eaten by small fish and small fish by larger fish that people eat
Harmful chemicals build up at each level of the food chain, so the highest amounts reach the animals and people at the top.
Q23The table compares two plans for a colony celebration. Which plan is better for the environment and for the neighbours?
DPlan B
It uses a clay idol and natural colours, which keep the water clean, and it stops loud music by 10 p.m., which respects the noise rules.
Q24The picture shows flowers and leaves being sent to a compost pit. Which step will reduce the festival waste going to a landfill the most?
CCollecting flowers and leaves separately so that they can be composted
Most festival waste is plant waste, and composting turns it into useful manure instead of landfill.
Q25Your colony is planning the celebration shown in the picture. Which decision best shows respect for everyone in the colony?
CKeep the mandap open to the whole colony and keep the music within the permitted hours
A community festival should include everyone without disturbing anyone.
Secondary Stage
Grades 9 - 10 • 25 questions • 25 marksQuick answer grid
Detailed key with explanations
Q1The diagram shows what happens when plaster of Paris is mixed with water while making an idol. Which compound is formed in the box marked '?'
AGypsum, CaSO4 . 2H2O
Plaster of Paris takes up water and sets as gypsum, a hard solid that does not dissolve, which is why plaster idols remain on the bed of a lake.
Q2The table lists pigments used on festival idols and the metals present in them. Paint washed off the idols enters the lake. Which pigment adds two toxic heavy metals to the water?
BChrome yellow
It carries both lead and chromium, and both are toxic heavy metals that build up in living tissue.
Q3The table shows the pH of a lake before, during and two weeks after the immersions. What does this change indicate?
DThe water became more alkaline
The pH rose from 7.1 to 8.9, and a pH above 7 and rising means increasing alkalinity.
Q4The graph shows the dissolved oxygen (DO) and biochemical oxygen demand (BOD) of a lake over four weeks, with the immersions held in week 3. Which conclusion is best supported by the data?
CThe organic and chemical load rose, leaving less oxygen for aquatic life
DO fell from 8 to 3 mg/L while BOD rose from 2 to 9 mg/L, and a high BOD means micro-organisms are using up the oxygen.
Q5The pyramid shows the concentration of a paint chemical at different levels of a lake food chain. How many times greater is the concentration in large fish than in the lake water?
B250 times
5.00 ppm divided by 0.02 ppm = 250. This build-up along a food chain is called biomagnification.
Q6The sound level at a mandap rose from 80 dB to 110 dB, as marked on the scale. By what factor did the sound intensity increase?
C1000 times
The rise is 30 dB, and each 10 dB step multiplies the intensity by 10, so the factor is 10 x 10 x 10 = 1000.
Q7An idol of volume 0.05 m3 is fully immersed in the tank shown. Taking the density of water as 1000 kg/m3 and g as 10 m/s2, what is the upthrust on the idol?
A500 N
Upthrust = weight of water displaced = V x d x g = 0.05 x 1000 x 10 = 500 N.
Q8An idol weighing 2000 N is pushed up the ramp shown, which is 5 m long and 1 m high. Ignoring friction, what is the least effort needed?
D400 N
For an inclined plane, effort x length = load x height, so effort = (2000 x 1) / 5 = 400 N. The work done stays the same; only the force needed is reduced.
Q9A modak is modelled as a cone of radius 3 cm and height 7 cm, as shown. Taking pi as 22/7, what is its volume?
A66 cm3
Volume of a cone = (1/3) x pi x r2 x h = (1/3) x (22/7) x 9 x 7 = 66 cm3.
Q10A conical mandap tent has a base radius of 7 m and a height of 24 m, as shown. Taking pi as 22/7, how much cloth is needed for its curved surface?
C550 m2
Slant height l = square root of (49 + 576) = 25 m, and curved surface area = pi x r x l = (22/7) x 7 x 25 = 550 m2.
Q11The table shows the number of idols immersed at a tank on six days. What is the mean number of idols immersed per day?
B60
The total is 40 + 55 + 60 + 75 + 50 + 80 = 360, and 360 divided by 6 = 60.
Q12The table shows the idols made in a ward, by material. One idol is picked at random for a quality check. What is the probability that it is NOT a clay idol?
D2/5
Idols that are not clay = 60 + 40 = 100, so the probability is 100/250 = 2/5.
Q13From a point 30 m from the foot of a platform, the angle of elevation of the top of the idol is 30 degrees, as shown. What is the height of the top of the idol above the eye level?
A17.3 m
Height = 30 x tan 30 = 30 / (square root of 3) = 10 x square root of 3, which is about 17.3 m.
Q14A city produced 500 tonnes of festival waste in 2024 and set the target shown in the picture. If the target is met each year, how much waste will be produced in 2026?
C320 tonnes
2025: 500 x 0.8 = 400 tonnes, and 2026: 400 x 0.8 = 320 tonnes.
Q15The histogram shows sound-level readings taken during a procession. Which is the modal class of the data?
A80-90 dB
This class has the highest frequency, 12 readings, so it is the modal class.
Q16The graph shows the turbidity of a lake over five days, with immersions on day 3. Between which two days did the turbidity rise the most?
CDay 2 and Day 3
The turbidity rose from 14 NTU to 45 NTU, an increase of 31 NTU, which is far greater than any other change.
Q17The table lists the rules set by a city for the festival. A committee does the four things listed in the options. Which one breaks a rule in the table?
BRunning loudspeakers until 12:30 a.m.
The city allows loudspeakers only up to 10 p.m., so the other three actions follow the rules.
Q18The flow chart shows how a complaint about polluted lake water is dealt with. Which body is mainly responsible for enforcing water pollution control within a state under the Water Act, 1974?
BThe State Pollution Control Board
It monitors water quality, sets conditions and takes action within the state, while the Central Board coordinates across states.
Q19The table compares three idol materials on three counts. A committee wants the least lasting harm to the lake at a low cost. Which material should it choose?
CPaper pulp
It breaks up in one day, leaves no residue and costs little. Clay is a good second choice, but plaster leaves hard toxic pieces for months.
Q20The table shows two options before a city corporation. If artificial tanks are built and the lake therefore needs no clean-up, how much does the corporation save in a year?
DRs. 18 lakh
The saving is Rs. 30 lakh minus Rs. 12 lakh = Rs. 18 lakh, besides the benefit of a cleaner lake.
Q21A heavy idol of weight 1200 N is lifted using the pulley arrangement shown, in which four rope sections support the load. Ignoring friction, what effort is needed?
A300 N
The mechanical advantage equals the number of supporting rope sections, so effort = 1200 / 4 = 300 N, but the rope must be pulled through four times the distance.
Q22Three beakers were set up as shown and left for 24 hours at the same temperature. Which beaker is the control in this experiment?
CBeaker C
It holds water alone, so any change seen in A and B can be attributed to the material added and not to the water itself.
Q23The graph shows the number of visitors at an immersion point through the evening. At which time should the largest number of volunteers be deployed?
D7-8 p.m.
The crowd peaks at about 1100 visitors in this hour, so the risk of crowding is highest then.
Q24The table shows three plans placed before a colony committee. Which plan meets both the environmental and the noise requirements?
BPlan 2
Only Plan 2 uses a clay idol, immerses it in an artificial tank and stops the music by 10 p.m. Plan 1 fails on the idol and the lake, and Plan 3 fails on the music and the lake.
Q25The picture shows the immersion point of a colony on the final day. Which arrangement best protects the crowd while keeping the celebration open to everyone?
DKeep a barricaded walkway, trained volunteers at the water's edge and a separate viewing area for children and elders
This keeps everyone included while keeping the crowd away from deep water.
