A cylinder of height h is 2/3 of water. When all of the water is poured into an empty cylinder whose radius is 25 percent larger than that of the original cylinder, the new cylinder is 3/5 full. The height of the new cylinder is what percent of h?
Choose the correct choice.
A) 25% B) 50% C) 60% D) 80% E) 90%
Basically we can disregard the radius is 25% information, as we are only asked about the height of the original and the new cylinder.   This is becausethe new cylinder is 3/5 fullmeans the same as that it's height is 3/5.   Original cylinder 2/3   New cylinder 3/5   So 3/5/2/3 = 3/5*3/2=
