Henry completed 5/8 of the questions in a quiz in the first hour. He managed to complete another 13 questions in the second hour and the ratio of the question that were unanswered to the questions that were answered became 1 : 6. What was the total number of questions in the quiz?

x = total questions

 

questions answered = 5/8 x + 13

  and this is   6 out of (6+1) = 7    or  6/7 of the total

 

5/8 x + 13 = = 6/7 x

x = 56 questions
