question: If Rs. 510 be divided among A, B, C in such a way that A gets 2/3 of what B gets and B gets 1/4 of what C gets, then their shares are respectively:
Options:
(A) Rs. 60, Rs. 90, Rs. 389
(B) Rs. 60, Rs. 90, Rs. 360
(C) Rs. 60, Rs. 90, Rs. 368
(D) Rs. 60, Rs. 90, Rs. 329
(E) Rs. 60, Rs. 30, Rs. 329
answer: Stream of consciousness: (A = 2/3 B and B = 1/4 C) = A/B = 2/3 and B/C = 1/4
A:B = 2:3 and B:C = 1:4 = 3:12
A:B:C = 2:3:12
A;s share = 510 * 2/17 = Rs. 60
B's share = 510 * 3/17 = Rs. 90
C's share = 510 * 12/17 = Rs. 360. The answer is (B).

a: Stream of consciousness: Number of times wheel moves in 1 hour = 20 * 60 = 1200
:. Distance moves = (1200*35) cms = 42000 cms
In metres = 420 metr The answer is (E).

question: In a question on division with zero remainder, a candidate took 12 as divisor instead of 21. The quotient obtained by him was 35. The correct quotient is:
Options:
(A) 15
(B) 18
(C) 20
(D) 22
(E) 24
answer: Stream of consciousness: Number = (35 * 12) = 420
Correct quotient = 420/21 = 20 The answer is (C).

question: What amount does Kiran get if he invests Rs. 18000 at 15% p.a. simple interest for four years?

answer:
Stream of consciousness: Simple interest = (18000 * 4 * 15)/100 = Rs. 10800
Amount = P + I = 18000 + 10800 = Rs. 28800 The answer is (D).
