Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: The number of ripe mangoes from the tree is 3 / 5 * 400 = 240. If Lindsay eats 60% of the ripe mangoes, she eats 60 / 100 * 240 = 144 mangoes. The total number of ripe mangoes remaining is 240 - 144 = 96.
 The question and answer:
3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with.
The answer is 96
