CBSE Class 3 Mathematics NCERT Solutions: Jugs and Mugs

This question asks for a personal estimation of daily water intake. The amount of water a person drinks can vary greatly depending on factors like weather, activity level, and personal habits.

For example, during warmer months or when engaging in physical activities, one might drink more water. Conversely, during colder months, the need for water might be less.

A reasonable estimate for daily water intake could be around 5 to 10 glasses, depending on these conditions.

Answer: During summer, I drink about 10 glasses of water in a day. During winter, I drink about 5 glasses of water in a day.

This question relates to the body's water balance. The body loses water through various processes like sweating, breathing, and urination. The amount of water lost is generally related to the amount consumed and the body's needs.

A common understanding is that a significant portion of the water consumed is eventually eliminated by the body. A reasonable guess would be that roughly half of the water taken in is expelled.

Answer: I guess about half of the water taken by me goes out of my body.

Observing the context of the chapter 'Jugs and Mugs', Naima and Jeetu are engaged in an activity related to measuring or comparing the capacity of containers. The image and the subsequent questions suggest they are pouring water into jugs.

Answer: Naima and Jeetu are pouring water into jugs to measure or compare their capacities.

This is a statement expressing an opinion or an estimation about the capacity of Naima's jug. The student is stating their belief that Naima's jug can be filled by pouring approximately 3 glasses of water into it.

Answer: The student believes that Naima's jug has a capacity equivalent to about 3 glasses of water.

To determine whose jug holds more water, we need to compare the estimated or measured capacities of Naima's and Jeetu's jugs. Based on the provided answers, Jeetu's jug is estimated to hold more water than Naima's.

Answer: Jeetu's jug holds more water.

This question asks for an estimation of the capacity of Jeetu's jug in terms of glasses of water. Following the context where Jeetu's jug is larger than Naima's (which holds about 3 glasses), a reasonable estimate for Jeetu's jug would be more than 3 glasses.

Answer: Four glasses of water.

This statement provides information about the capacity of Jeetu's jug. It implies that if Jeetu adds one more glass of water to whatever is already in his jug, it will reach the halfway mark. This suggests that the total capacity of Jeetu's jug is approximately double the amount of water plus one glass.

Answer: If Jeetu pours one more glass of water his jug will be around half full.

This question compares the number of trips Naseem and Abdul made, presumably to fetch water. If Naseem made more trips, it indicates that her container (bottle) was smaller than Abdul's, requiring her to refill it more often to carry the same total amount of water or complete her task.

Answer: Naseem's bottle is smaller in size and so she had to go more number of times.

From the previous question, we know Naseem made more trips because her bottle is smaller. If her bottle is smaller, it holds less water than Abdul's. Specifically, if she made roughly twice the number of trips for a similar task, her bottle might hold about half the amount of Abdul's.

Answer: Naseem's bottle can hold half as much water as Abdul's bottle.

We are given that Pot B holds 11 glasses of water. Pot A holds twice as much water as Pot B. To find the capacity of Pot A, we need to multiply the capacity of Pot B by 2.

Capacity of Pot B = 11 glasses

Capacity of Pot A = 2 × Capacity of Pot B

Capacity of Pot A = $11\; \backslash times\; 2$ glasses

Capacity of Pot A = 22 glasses

Answer: 22 glasses of water are needed to fill pot A.

This question requires visual identification from a picture (which is not provided in the text). Assuming the picture shows potholes labeled A, B, and C, the student needs to visually assess their sizes. The answer indicates that 'B' is identified as the largest.

Answer: 'B' is the biggest pothole.

We are told that hole A requires 5 jugs to be filled. The question implies a relationship between the sizes of hole A and hole B, likely based on the visual context or prior information not fully present. The provided solution suggests that hole B needs double the amount of pebbles compared to hole A. Therefore, to find the number of jugs needed for hole B, we multiply the number of jugs for hole A by 2.

Jugs for hole A = 5

Jugs for hole B = 2 × Jugs for hole A

Jugs for hole B = $5\; \backslash times\; 2$

Jugs for hole B = 10

Answer: 10 jugs of pebbles are needed to fill hole B.
