Monthly rent on an apartment rises from $850 to $918. By what percent did the rent increase?

Correct answer to question 6 (Arithmetic Reasoning): 8 percent

Method

Percent change compares the increase to the original amount, not the new one. The rent went up by 918 - 850 = 68 dollars, and 68 divided by 850 is 0.08, which is 8 percent.
