Answer this question:The average number of fruits per basket in five baskets is 25. If basket A contains 15 apples, B has 30 mangoes, C has 20 peaches, D has 25 pears and E has some bananas, how many bananas are in basket E?
Each basket contains an average of 25 fruits so the 5 baskets in all contain 25 * 5 = 125 fruits. The number of apples, mangoes, peaches and pears is 15 + 30 + 20 + 25 = 90. The remaining fruits are bananas and they are 125 - 90 = 35 in number.
The answer is 35.

Answer this question:John and Sam were hungry so they ordered an extra-large pizza that was pre-sliced into 12 pieces. John ate 3 slices while Sam ate twice the amount that John ate. How many slices of pizza were left?
Sam had twice the amount of John so Sam ate 3 * 2 = 6 slices. Together, they ate 3 + 6 = 9 slices. 1 pizza has 12 slices. 9 slices were eaten so 12 - 9 = 3 slices left.
The answer is 3.

Answer this question:John takes 3 naps a week. Each nap is 2 hours long. In 70 days how many hours of naps does he take?
There are 70 / 7 = 10 weeks in 70 days. So he takes 10 * 3 = 30 naps. That means he naps for 30 * 2 = 60 hours.
The answer is 60.

Answer this question:The county fair was hosting a pumpkin contest to see who could grow the biggest pumpkin in pounds. Brad entered his pumpkin with a weight of 54 pounds. Jessica's was half the weight of Brad's. Betty's pumpkin weight 4 times the amount of Jessica's pumpkin. What is the difference between the heaviest and lightest pumpkin in pounds?
Jessica's pumpkin weighs half the weight of Brad's 54 - pound pumpkin so 54 / 2 = 27 pounds. Betty's pumpkin weighs 4 times the amount of Jessica's 27 - pound pumpkin so it weighs 4 * 27 = 108. Betty has the heaviest pumpkin at 108 pounds while Jessica's is the lowest at 27 pounds so the difference is 108 - 27 = 81 pounds.
The answer is 81.
