q: X can finish a work in 24 days. Y can finish the same work in 16 days. Yworked for 10 days and left the job. how many days does X alone need to finish the remaining work?
Options:
(A) 3
(B) 5
(C) 6
(D) 8
(E) 9
a: Stream of consciousness: Work done by X in 1 day = 1/24
Work done by Y in 1 day = 1/16
Work done by Y in 10 days = 10/16 = 5/8
Remaining work = 1 – 5/8 = 3/8
Number of days in which X can finish the remaining work = (3/8) / (1/24) = 9 The answer is (E).


question: Which of the following is a prime number ?
Options:

(C) 80
(D) 81
(E) 90
a: Stream of consciousness: 44 + 28 + 10 = 82%
100 – 82 = 18%
450 * 18/100 = 81 The answer is (D).
