A cylinder of height h is 8/9 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?  Choices.
A) 25%	B) 50%	C) 68%	D) 80%	E) 100%
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 8/9   New cylinder 3/5   So 3/5/8/9 = 3/5 * 9/8 = 12/15 = 4/5 = 0.680 or 68%.   Answer 68%
