Mr Kevin was sitting for his driving theory test. In the first hour, he had completed 1/3 of the questions. By the next hour, he answered another 14 questions. The ratio of the questions answered to the ratio of the questions not answered became 4:1. How many questions were there in the test?

Answer 1

If there were x questions, then
1/3 x + 14 questions were answered.
So 2/3 x - 14 were left unanswered
1/3 x + 14 = 4(2/3 x - 14)
now just solve for x
