If the ratio of selected to unselected candidates was 14 : 25. If 35 less had applied and 10 less selected, the ratio of selected to unselected would have been 3 : 5. What is the Number of candidates who had applied for a job?
Answer & explanation
Correct answer: option 4
Let the number of selected candidate be 14x and the number of unselected candidates be 25x, number of candidates is 195 who had applied for a job.
So, the total number of applied candidates is 14x + 25x = 39x
According to the question,
If 35 less applied, then resulting number of candidates applied is (39x - 35)
And 10 less candidates got selected, then the resulting no. of candidates selected is (14x - 10).
So, the resulting no. of unselected candidates is (applied - selected)
⇒ (39x - 35) - (14x - 10)
⇒ 25x - 25
Now, the given ratio of resulting selected to the resulting unselected candidates is 3 : 5
So, \(\frac{14x - 10}{25x - 25}\) = \(\frac{3}{5}\)
⇒ x = 5,
So, the number of candidates who had applied = 39x
⇒ 39 x 5 = 195.
Therefore number of candidates who applied for job are 195.
