Henry eats X scones in X percent of the time it takes Rachel to eat Y scones. If Rachel eats four scones in ten minutes, then the number of minutes it takes Henry to eat 2 scones must be equal to which of the following?
Choose the correct choice from the following answers
A) Y/20  B) 200/Y  C) 100Y/(15X)  D) XY/250  E) Y/(5X)
Rachel eats 4 scones/10 minutes = 2/5 scones per minute   The time for Rachel to eat 1 scone is 5/2 minutes.   The time for Rachel to eat Y scones is 5Y/2 minutes.   The time for Henry to eat X scones is 5YX/200 minutes.   The time for Henry to eat 1 scone is 5Y/200 minutes.   The time for Henry to eat 2 scones is 10Y/200 = Y/20 minutes.   The answer is Y/20.
