Jar A has 16% more marbles than Jar B . What percent of marbles from Jar A need to be moved into Jar B so that both jars have equal marbles?
Choose the most appropriate option:  A) 5%  B) 7%  C) 9%  D) 11%  E) 13%
An easy way to solve this question is by number plugging. Assume there are 100 marbles in Jar B then in Jar A there will be 116 marbles. Now, for both jars to have equal marbles we should move 8 marbles from A to B, which is 8/116=~7% of A.   Answer: 7%.
