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? Think carefully first, then make a decision:
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. So, the answer is 35.
