Mira was sitting for her driving theory test which consisted of multiple choice questions. By the first hour, she completed 2/5 of the questions. After another half an hour, she managed to answer another 14 questions and the ratio of the number of question that were answered to those that were unanswered became 3:1. How many questions were there in the driving theory test?

25 x   + 14   =  3 out of (3+1) x = 3/4 x     where x = number of questions

 

2/5 x + 14 = 3/4 x
