a: Stream of consciousness: Total number of votes polled = (6136 + 7636 + 11628) = 25400

Options:
(A) 22
(B) 27
(C) 15
(D) 77
(E) 16
answer: Stream of consciousness: Total members in the group = 7
Average amount = Rs. 20
Total amount with them = 7 * 20 = Rs. 140

The average amount with them = 90/6 = Rs. 15. The answer is (C).

C's 1 hour work = (7/12 - 1/2) = 1/12
C alone will take 12 hours to do the work. The answer is (A).
