After a 15 percent pay raise, a technician's new hourly wage is $27.60. What was the wage before the raise?

Correct answer to question 151 (Arithmetic Reasoning): $24.00

Method

The new wage represents 115 percent of the old one, so divide rather than subtract a straight 15 percent. Dividing 27.60 by 1.15 gives the original wage of $24.00.
