What is the Number of candidates who had applied if the ratio of selected to unselected was 14 : 25. If 35 less had applied and 10 less selected, the ratio of selected to unselected would have been 3 : 5?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 195
Let the selected and unselected candidates be 14x and 25x respectively
Total candidates applied = 14x + 25x = 39x
According to the question,
(39x - 35)/(14x - 10) = 8/3
117x - 105 = 112x - 80
5x = 25
x = 5
No. of candidates who applied = 39 × 5 = 195
