Draw a face with fish eyes.
Ans.
Fishes can have very different sizes. The smallest fish is about 1 cm long. How long is the biggest fish you can imagine? ______
Ans. 15 m
How many times longer is your big fish than the smallest fish?
Sol. Length of biggest fish = 18 m = 1800 cm
Length of smallest fish = 1 cm
Since 1 metre = 100 centimetre
Hence, 18 metre = 18 x 100 centimetre = 1800 centimetre Hence, the longest fish is 1800 times longer than the smallest fish.
About how many kilograms do you weigh?
Ans. I weigh about 32 kg
So, 12 children like you put together will weigh about _______
Sol. Weight of 1 child = 32 kg
Weight of 12 child = 12 x 32 = 384 kg
About how much more does the whale shark weigh than 12 children like you put together?
Sol. Weight of a whale shark fish = 16000 kg
Weight of 12 children = 384 kg
Difference in Weights = 16000 kg – 384 kg = 15616 kg
Whale shark fish will weigh 15616 kg more than the weight of 12 children.

Fishermen in their Boats
Close your eyes and imagine the sea with waves rising high.
Ans. Do it yourself.
How high do you think the waves can go?
Ans. 2 m.
These log boats do not go very far. If the wind is helpful, they travel
about 4 km in one hour.
How long will take to go a distance of 10 km?
Sol. Distance covered by log boats in 1 hour = 4 km
Distance covered by log boats in 2 hours = 2 × 4 km = 8 km
Distance 2 km is covered in ½ hour.
So, the distance of 10 km is covered in 2 and a half hours.
Guess how far you can go in one hour if you wake fast?
Ans. About 4 km.

Look at the sun and find out the direction from where it rises.
From where you are, what interesting thing do you see to your east?
Ans. I see the rising sun in the east.
Name two things that are lying to your west.
Ans. Glass, table
What a Catch!
Look at different types of boats. Some boats have motors and go farther into the sea. Since they go far out they can catch more fish. These boats travel faster, at the speed of about 20 km in one hour.
How far would the motorboats go in three and a half hours?
Sol. Motorboats go in 1 hour = 20 km
Distance covered by motor boats in 3 hours = 3 × 20 km = 60 km
Distance covered by motor boats in a half hour = 20/2 = 10 km
Motor boats go in 3 and a half hours = (60 + 10) km = 70 km
How much time will they take to go 85 km?
Sol. A distance of 20 km is covered by a motor boat in 1 hour.
A distance of 1 km is covered by a motor boat in = 1/20 hours
A distance of 85 km is covered by a motorboat in = 1/20 × 85 hours = 17/2 hours = 4 and ¼ hours = 4 hours and 15 minutes.

Write a news report about the dangers faced by the fish in our rivers and seas.
Ans. Big machine boats or trawlers pose a big danger to the fish population and to small fishermen.
These trawlers catch thousands of kilograms of fish including small baby fish. There is a great danger of being left with no fish in the sea including the small baby fish which have yet to grow. The government should take care of the sea and its fish and prohibit the use of trawlers.
Big trawlers hamper the natural growth of the fish population in the ocean. They are also a threat to the livelihood of traditional fishermen.
Which boat gets how much?
Type of boat | Catch of fish in one trip in (kg) | Speed of the boat (how far it goes in one hour) |
---|---|---|
Long boat | 20 kg | 4 km per hour |
Long tail boat | 600 kg | 12 km per |
Motor boat | 800 kg | 20 km per hour hour |
Machine boat | 6000 kg | 22 km per hour |
(a) About how much fish in all will each type of boat bring in seven trips?

Some Big, Big Numbers!
In Class IV Merry Math you heard of the number “lakh” which is equal to a hundred thousand. You have read that there are about one lakh brick kilns in our country, where bricks are made.
What other things have you heard of in lakhs?
Ans. I have heard of the following things in lakhs:
Population of town, Money a person has, cost of a house, cost of a car.
Write the number one thousand. Now write one hundred thousand. So, how many zeroes are there in the number one lakh?
Sol. One thousand =1000
One hundred thousand = 100,000
Number of zeroes in the number one lakh = 5
There are about two lakh boats in our country. Half of them are without a motor. What is the number of boats with a motor?
Sol. Total number of boats in our country = 2,00,000
Number of boats without a motor = ½ × 200000 = 100,000
The number of boats with a motor = 2,00,000 – 1,00,000 = 1,00,000
About one-fourth of the boats with a motor are big machine boats. How many thousand machine boats are there? (Do it without writing down)
Ans. Number of motor boats = 100000
1/4 × 100000 = 25000
Hence, number of machine boats = 25000 (twenty-five thousand)
Where have you heard of a crore? What was the number used for?
Ans. I have heard of a crore in an L.E.D. (TV). The number was used for the population of India.

The Fish Market
Have you been to a fish market? If you have then you might know why a very noisy place is sometimes called a ‘fish market’!
This fish market is busy today.
Many boats have brought a good catch. The fisherwomen are shouting out their prices to the buyers.
Mini — “Come here! Come here! Take sardines at ₹ 200 a kg”
Gracy — “Never so cheap! Get sword-fish for ₹ 160 a kg”
Vimla sells prawns for ₹ 250 a kg. Kamla sells squid for ₹ 150 a kg.
Look, Fazila can hardly carry this big kingfish! She says, “This fish weighs 8 kg. I will sell the whole for 1200”
Practice Time
1. At what price per kg did Fazila sell the kingfish?
Sol. She sells 8 kg of kingfish for = ₹ 1200
She sells 1 kg kingfish for = ₹ 1200/8 = ₹ 150
So, she sells kingfish for ₹ 150 per kg.
2. Vimla has sold 10 kg of Prawns today. How much money did she get for that?
Sol. Vimla sells, 1 kg Prawn for = ₹ 250
Vimla sells 10 kg Prawn for = ₹ 250 × 10 = ₹ 2500
3. Gracy sold 6 kg of swordfish. Mini has earned as much money as Gracy. How many kg of sardines did Mini sell? (Gracy sells swordfish for 160 per kg. Mini sells sardine at 200 per kg).
Sol. Gracy sells 1 kg swordfish for = ₹ 160
Total swordfish sold by Gracy = 6 kg
So, Gracy has earned money = ₹ 160 × 6 = ₹ 960
Mini earns total money = Money Gracy has earned
Total money earned by Mini = ₹ 960
Mini sells 1 kg sardines for = ₹ 200 per kg
Total weight of sardines sold by Mini = 960/200 = 4.8 kg

4. Basheer has 1500. He spends one-fourth of the money on squid and another three-fourths on Prawns.
(a) How many kilograms of squid did he buy? (Rate of squid is ₹ 150 per kg)
(b) How many kilograms of Prawns did he buy? (Rate of Prawns is ₹ 250 per kg)
Sol. Total amount Basheer has = ₹ 1500
Amount spent on squid = 1/4 × ₹ 1500 = ₹ 375
Amount spent on prawns = 3/4 × ₹ 1500 = ₹ 1125
(a) Cost of squid per kg = ₹ 150
Number of kilograms of squid he bought for ₹ 375
Total amount spent on squid/Cost of squid per kg = 375/150 = 2.5 kg
(b) Cost of prawns per kg = ₹ 250
Number of kilograms of prawns he bought for ₹ 1125
Total amount spent on prawns/Cost of prawns per kg = 1125/250 = 4.5 kg
Women’s Co-operative Bank
The meeting of the Co-operative Bank has just begun. Fazila is the president. Twenty fisherwomen have made their own bank. Each saves ₹ 100/- every month and puts it in the bank.
How much money does the group collect each month?
Sol. Money collected from 1 fisherwoman in one month = ₹ 100
Number of fisherwomen = 20
Money collected by the group = ₹ 100 × 20 = ₹ 2000.
How much money will be collected in ten years?
Sol. Number of years = 10
Number of months in 1 year = 12
Total number of months in 10 years = 10 × 12 = 120
Money collected in 1 month = ₹ 2000
Total money collected in 10 years = ₹ 2000 × 120 = ₹ 240000

Number of months in 1 year = 12
Money paid back to the bank = ₹ 345 × 12 = ₹ 4140
(b) Zaina and her sister took a loan of 21,000 to buy a long boat. They paid back a total of ₹ 23,520 in one year. How much did they pay back every month?
Sol. Money paid back in one year = ₹ 23,520
Number of months in one year = 12
Money paid back every month = ₹ 23,520/12 = ₹ 1960
Why Don’t We Start a New Fish-drying Factory?
The women of the Co-operative Bank also want to start a factory to dry fish. The Panchayat has given them some land for that. Over the years they have saved ₹ 74,000. They find out how much they will need for the factory.
Fazila writes the things they need to buy to begin. See the table for the cost of each item and the number of items they want to buy. Find the total cost.

When fresh fish is dried it becomes 1/3 its weight.
In one month they plan to dry 6000 kg of fresh fish.
How much-dried fish will they get in a month? ____________
Ans. The amount of dried fish dried in one month = 6000 kg × ⅓ = 2000 kg
Vimla — Let us first calculate for 6 kg of fresh fish.
We buy fresh fish for | ₹ 150 per kg |
---|---|
We sell dried fish for | ₹ 700 per kg |
We dry 6 kg fresh fish to get _____ kg dried fish
Ans. We dry 6 kg fresh fish to get 6 kg × ⅓ = 2 kg dried fish
For 6 kg fresh fish we have to pay 6 × __ = ₹ 900
Ans. For 6 kg fresh fish we have to pay = 6 × ₹ 150 = ₹ 900
We will sell 2 kg dried fish and get 2 × __ = ₹ __
Ans. We will sell 2 kg of dried fish and get 2 × ₹ 700 = ₹ 1400
So if we dry 6 kg fresh fish we will earn __ – 900 = ₹ __
Ans. So, if we dry 6 kg of fresh fish we will earn ₹ 1400 – ₹ 900 = ₹ 500
But if we dry 6000 kg we can earn ₹ __ × 1000 in one month!
Ans. But if we dry 6000 kg we can earn = ₹ 500 × 1000 in one month!
Zaina I found that for 6000 kg of fish, we would need 1500 kg salt every month! Its price is 15 per kg.
Monthly costs :
- a) Salt 1500 × 2 = ₹ ____
Ans. Salt 1500 × ₹ 15 = ₹ 22500
(b) Packing and bus charges = ₹ 7500
So the total monthly cost of drying, packing and bus charges = ₹ ____
Ans. So the total monthly cost of drying and selling the fish = ₹ 30,000
Fazila — That sounds very good! Our calculations tell us that every month our Bank will earn 470,000.
Check to see if you also get the same answer.
Sol. Money earned = ₹ 500 × 1000 = ₹ 5,00,000
Money spent = ₹ 30,000
Profit =₹ 5,00,000 – ₹ 30,000 = ₹ 4,70000
