## Solution
Formula = ab
A = 25 and B = 36
2536 = 5 6 = 30
## What the question and answer could be

Options:
(A) A) 59
(B) B) 30
(C) C) 63
(D) D) 65
(E) E) 67
(B)

## Solution
A's 1 hour work = 1/4;
(B + C)'s 1 hour work = 1/3;
(A + C)'s 1 hour work = 1/2
(A + B + C)'s 1 hour work = (1/4 + 1/3) = 7/12
B's 1 hour work = (7/12 + 1/2) = 1/12
B alone will take 12 hours to do the work.
## What the question and answer could be
