q: A man purchased 3 blankets @ Rs.100 each, 5 blankets @ Rs.150 each and two blankets at a certain rate which is now slipped off from his memory. But he remembers that the average price of the blankets was Rs.150. Find the unknown rate of two blankets?
Options:
(A) 288
(B) 299
(C) 266
(D) 450
(E) 291
a: Stream of consciousness: 10 * 150 = 1500
3 * 100 + 5 * 150 = 1050
1500 1050 = 450 The answer is (D).

question: A number when divided by 221 gives a remainder 43, what remainder will be obtained by dividing the same number 17?
Options:
(A) 11
(B) 10
(C) 9
(D) 8
(E) 7
answer: Stream of consciousness: 221 + 43 = 264/17 = 9 (Remainder) The answer is (C).

q: What approximate value should come in place of question mark (?) in the following equation
287.532 + 1894.029 657.48 = 543.095 + ?
Options:
(A) 870
(B) 790
(C) 980
(D) 770
(E) 890
a: Stream of consciousness: ? = 285 + 1895 655 545 or, ? = 980 The answer is (C).

question: The no. of girls in a class are seven times the no. of boys, which value cannever be the of total students?
Options:
(A) 2
(B) 5
(C) 8
(D) 9
(E) 10
answer: Stream of consciousness: Let the boys are X, then girls are 7X, total = X+7X = 8X
So it should be multiple of 8, 30 is not a multiple of 8. The answer is (C).

q: 10 people meet and shake hands. The maximum number of handshakes possible if there is to be no "cycle" of handshakes is (A cycle of handshakes is a sequence of k people a1, a2, , ak (k > 2) such that the pairs {a1, a2}, {a2, a3}, , {ak-1, ak}, {ak, a1} shake hands).
Options:
(A) 7
(B) 6
(C) 9
(D) 8
(E) 10
a: Stream of consciousness: The question is not written in proper manner but we can work in 3 methods
1) If these are random handshakes, then total methods = 10*9/2*1 = 45
2) If these are cyclic handshakes, then total methods = 10
3) If these persons are not cyclic but they are arranged in a straight bench, then number of methods = 9 The answer is (C).

q: Two trains are moving at 85 kmph and 70 kmph in opposite directions. Their lengths are 150 m and 100 m respectively. The time they will take to pass each other completely is?
Options:
(A) 5 25/31 sec
(B) 7 1/17 sec
(C) 7 2/2 sec
(D) 8 1/2 sec
(E) 7 1/9 sec
a:
Stream of consciousness: 70 + 85 = 155 * 5/18 = 775/18 mps
D = 150 + 100 = 250 m
T = 250 * 18/775 = 180/31 = 5 25/31 sec The answer is (A).
