In an MBA selection process, the ratio of selected to unselected was 11:2. If 40 less had applied and 20 less selected, the ratio of selected to unselected would have been 10:1. How many candidates had applied for the process?

 selected candidates = 11x

unselected candidates = 2x

total candidates = 13x

If 40 less had applied and 20 less selected, the ratio of selected to unselected would have been 10:1

then applied candidates = 13x - 40

selected candidates = 11x - 20

unselected candidates = 13x - 40 -(11x - 20) = 2x - 20

ratio of selected to unselected = 10:1

(11x-20)/(2x-20) = 10/1

11x - 20 = 20x - 200

9x = 180

x = 20

candidates applied = 13x = 13(20) = 260

So the answer is option B.
