Question: 1
The donkey asked 500 millilitres of kheer? Isn’t that more than a litre?
Answer:
The donkey asked, "Isn’t 500 millilitres of kheer more than a litre?"
The answer is: No, 500 millilitres of kheer is not more than a litre; it is actually less. One litre is equal to 1000 millilitres, so 500 millilitres is only half a litre. The fox clarified that 500 millilitres is half of 1000 millilitres, which equals one litre.
Question: 2
The donkey looked confused and asked – Ten glasses of 100 ml each. How much is that?
Answer:
Quantity of kheer in a glass = 100 mL
Quantity of kheer in 10 glasses = 10 × 100 mL
= 1000 mL
We know that,
1000 mL = 1 litre
Hence, 10 times 100 mL = 1 litre
Question: 3
Each ant drinks 1 millilitre of kheer.
So, 1000 ants drink: 1000 × 1 mL = _______ mL
Answer:
Given that each ant drinks 1 millilitre of kheer.
So, 1000 ants drink
=
1000 × 1 mL = 1000 mL
Therefore 1000 ants drink 1000 mL of kheer, i.e., 1 litre of kheer

Question: 10
How much water does his small bottle hold?
Answer:
He poured two small bottles of water to fill a 1-litre bottle.
We know 1 L = 1000 mL
2 small bottles = 1000 / 2 = 500 mL
So, his small bottle holds 500 mL of water.
Question: 11
Then how much water does Leela’s bottle hold?
Answer:
We know 1000 mL = 1 L
Big bottle’s capacity = 1000 mL
Leela uses the small bottle 5 times to fill the big bottle.
Small bottle’s capacity = 1000 / 5
= 200 mL
Hence, Leela’s bottle holds 200 mL of water.
Question: 12
Answer:
Ramu had two empty bottles: one small, with a capacity of 250 mL, and another large one. He started by filling the 250 mL bottle with water and pouring it into the large bottle, marking the level as 250 mL. He repeated this process, pouring another 250 mL of water, and marked the level as 500 mL.
After a third fill, he marked the level as 750 mL. When he filled the 250 mL bottle one more time and poured it into the large bottle, the water level reached 1 litre. By repeating this process, Ramu successfully created a large bottle with clear, accurate measurements of 250 mL increments.

My Measuring Bottle
Question: 13
Find your own way to make a bottle which can measure 200 mL, 400 mL, 600 mL, 800 mL and 1 litre. Discuss with your friends and teacher how you made this.
Answer:
To create a bottle that can measure 200 mL, 400 mL, 600 mL, 800 mL, and 1 litre, follow these steps:
Obtain Two Bottles
: Use a large bottle and a smaller bottle that has a capacity of 200 mL.
Marking the Levels
:
-
200 mL
: Fill the 200 mL bottle with water and pour it into the large bottle. Mark the water level as 200 mL on the large bottle.
-
400 mL
: Refill the 200 mL bottle and pour it into the large bottle. Mark the new water level as 400 mL.
-
600 mL
: Repeat the process by filling the 200 mL bottle and adding the water to the large bottle. Mark the water level as 600 mL.
-
800 mL
: Once more, fill the 200 mL bottle with water and pour it into the large bottle. Mark the water level as 800 mL.
-
1 Litre (1000 mL)
: Finally, fill the 200 mL bottle and pour the water into the large bottle. Mark the water level as 1 litre or 1000 mL.
By following these steps, you will create a measuring bottle with clear markings for 200 mL, 400 mL, 600 mL, 800 mL, and 1 litre. This method ensures that you can accurately measure these quantities of liquid.

Question: 15
Neetu has to take 3 injections in a day for 5 days. One injection gives 5 mL of the medicine to your body.
(a) How much medicine will she need for one day?
(b) How much medicine in all for 5 days?
Answer:
(a) One injection quantity = 5 mL of medicine
She has to take 3 injections in a day = 5 mL × 3
= 15 mL of medicine
Hence, for one day, she needs 15 mL of medicine.
(b) Quantity of medicine she is getting in a day = 15 mL
Quantity of medicine for 5 days = 15 mL × 5
= 75 mL
Therefore, she needs 75 mL of medicine in 5 days.

Question: 18
Amina’s water bottle holds one litre of water. She drank 250 mL of water and her friend Govind drank 150 mL. How much water is left in her bottle?
Answer:
Total water Amina’s bottle holds = 1 litre = 1000 mL
Total water drank = water drunk by Amina + water drunk by Govind
= 250 mL + 150 mL
= 400 mL
Water left in Amina’s bottle = 1000 mL – 400 mL
= 600 mL
Therefore, water left in Amina’s bottle is 600 mL
Question: 19
Yusuf runs a tea shop. For making a glass of tea he uses 20 mL of milk. Yesterday he made 100 glasses of tea. How much milk did he use?
Answer:
Milk used for making one glass of tea = 20 mL
So, for making 100 glasses of teas, milk used = 20 mL × 100
= 2000 mL

How many millilitres of medicine does she have to take every morning?
Answer:
Quantity of medicine Radha’s grandma has to take for 10 days = 200 mL
Medicine taken by her in a day = 200 / 10
= 20 mL
Hence, Radha’s grandma has to take 20 mL every morning

Water-Water
The table shows the water used in one day by a family of 5 people. They live in Goodallur village.
Question: 21
Total water used by them?
Answer:
Water used in cooking and drinking = 30 L
Water used in washing clothes = 40 L
Water used in cleaning pots, pans = 20 L
Water used in bathing = 75 L
Total water used = 30 L + 40 L + 20 L + 75 L
= 165 L
Therefore, total water used by them = 165 L

Question: 23
Is there any tap in your school or your home which is leaking?
Answer:
No, there is no tap which is leaking.
Question: 24
How much water do you think we waste through a leaking tap?
Answer:
I think nearly 40 litres of water is wasted through a leaking tap every day.
Question: 25
Place your litre jar below the leaking tap so as to catch all the drops in the bottle. Note the time. After one hour check how much water is in the bottle.
Answer:
After one hour, water collected in bottle = 1 L
Question: 26
Find out how much water is wasted in a day?
(a) In a week?
(b) In a month?
(c) In a year?
Answer:
In one hour, water wasted = 1 L
Therefore, in 24 hours, water wasted = 1 L × 24
= 24 L
Hence, 24 L of water is wasted in a day.
(a) Water wasted in a day = 24 L
Water wasted in 7 days = 24 L × 7
= 168 L
(b) Water wasted in a day = 24 L
Hence, in a month, which has 30 days, water wasted = 24 L × 30
= 720 L
(c) Water wasted in a month = 720 litre
The water wasted in 12 months or a year = 720 L × 12
= 8640 L
Chelannur village has a milk society. Geetha and Ammini went there to buy 4 litres of milk. But the man could not find the one litre measure. He had only a 3 litre and a 5 litre bottle with him. But he gave them exactly 4 litres of milk.
Question: 27
Explain how he did this.
To measure exactly 4 litres of milk using the bottles, follow these steps:
Initial Setup
: Start with a 5-litre bottle full of milk and an empty 3-litre bottle.
First Transfer
:
-
Pour milk from the 5-litre bottle into the 3-litre bottle until it is full.
-
This will leave 2 litres of milk in the 5-litre bottle.
Transfer to Geetha’s Bottle
:
-
Pour the remaining 2 litres from the 5-litre bottle into Geetha’s bottle.
Repeat the Process
:
-
Refill the 5-litre bottle with milk.
-
Again, pour milk from the 5-litre bottle into the 3-litre bottle until it is full.
-
This will leave another 2 litres of milk in the 5-litre bottle.
Second Transfer
:
-
Pour these 2 litres of milk into Geetha’s bottle.
