If 50 less had applied and 25 less selected, the ratio of selected to unselected would have been 9 : 4. So how many candidates had applied if the ratio of selected to unselected was 2 : 1.
Answer & explanation
Correct answer: option 3
Select : Unselect : Total (applied)
2 : 1 : 3
(ATQ) -25 - 50
----------- ----------------
9 : 4 13
Therefor
⇒ \(\frac{3R - 50}{2R - 25}\) = \(\frac{13}{9}\)
⇒ 27 R -450 = 26 R - 325
⇒ 1 R = 125
⇒ Total (applied) ⇒ 3 R = 125 × 3 = 375
