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 litreQuestion: 3
Each ant drinks 1 millilitre of kheer.

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.NCERT Solutions for Class 4 Maths Chapter 7 Jugs and Mugs Page No: 76
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.

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.
