If 50 less had applied and 25 less selected, the ratio of selected to unselected would have been 9 : 4. How many candidates had applied, if the ratio of selected to unselected was 2 : 1?1). 1252). 2503). 3754). 500

Answer»

Since the RATIO of selected to unselected was 2 : 1;

Selected CANDIDATES = 2x, Unselected candidates = x and total applied candidates = 3x

If 50 LESS had applied and 25 less selected, the ratio of selected to unselected would have been 9 : 4

∴ Total applied candidates = (3x – 50)

And Selected candidates = (2x – 25) and Unselected candidates = x – 50 + 25

∴ (2x – 25) / (x – 25) = 9/4

⇒ x = 125

∴ Total number of candidates who applied = 3x = 375
