a cylinder of height h is 6 / 7 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 ?
"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 6 / 7 new cylinder 3 / 5 so 3 / 5 / 6 / 7 = 3 / 5 * 7 / 6 = 0.70 or 70 % . answer d"
multiply(divide(divide(3, 5), divide(6, 7)), const_100)
