Question 2: Prabha is going to her grandmother, who lives in the next village. She wants to take 15 kg sugar cane, 7 kg apples and 8 kg tomatoes. She has to cross a river. In the boat, she can take 25 kg weight. Can she carry all the things?

Answer:Since Prabha wants to take 15 kg sugar cane,7 kg apples, and 8 kg tomatoes, the total weight of the things she wants to take is:
15 + 7 + 8 = 30 kg
We are given that she can carry 25 kg weight in the boat.
Since 30 is more than 25, she cannot carry all the things.

Question 3: Write the missing points.
Who is the winner this time?_______

Answer:Find the missing numbers.
Since 21 – 5 = 16, we can write 16 + 5 = 21
Since 32 – 8 = 24, we can write 24 + 8 = 32
16 + 13 = 29
Since 35 – 5 = 30, we can write 30 + 5 = 35
Since 30 – 7 = 23 , we can write 23 + 7 = 30
Therefore, the correct answer is:

Since the monkey scored the highest points, the monkey is the winner this time.
