(A) 8 2/5days
(B) 10 2/5days
(C) 6 2/5days
(D) 18 2/5days
(E) 17 2/5days
a: Stream of consciousness: A + B = 1/24 + 1/15 = 13/120
A + C = 1/24 + 1/12 = 1/8
13/120 + 1/8 = 28/120
4 1/5 days * 2 = 8 2/5days The answer is (A).

q: A person spends 1/3rd of the money with him on clothes, 1/5th of the remaining on food and 1/4th of the remaining on travel. Now, he is left with Rs 200. How much did he have with him in the beginning?
Options:
(A) s 200
(B) s 500
(C) s 300
(D) s 450
(E) s 550
a:
Stream of consciousness: Suppose the amount in the beginning was Rs 'x'
Money spent on clothes = Rs 1x/3 Balance = Rs 2x/3
Money spent on food = 1/5 of 2x/3 = Rs 2x/15
Balance = 2x/3 - 2x/15 = Rs 8x/15
Money spent on travel = 1/4 of 8x/15 = Rs 2x/15 = 8x/15 - 2x/15 = 6x/15 = Rs2x/5
Therefore 2x/5 = 200 = 500 The answer is (B).
