q: The average of 11 results is 50, if the average of first six results is 49 and that of the last six is 52. Find the sixth result?
Options:
(A) 22
(B) 56
(C) 88
(D) 66
(E) 21
a: Stream of consciousness: 1 to 11 = 11 * 50 = 550
1 to 6 = 6 * 49 = 294
6 to 11 = 6 * 52 = 312
6th = 294 + 312 550 = 56' The answer is (B).

question: A train 210 m long, running with a speed of 63 km/hr will pass a tree in?
Options:
(A) 15 sec
(B) 16 sec
(C) 18 sec
(D) 12 sec
(E) 25 sec
answer: Stream of consciousness: Speed = 63 * 5/18 = 35/2 m/sec
Time taken = 210 * 2/35 = 12 sec The answer is (D).

q: A no.when divided by 281 gives a remainder 160, what remainder will be obtainedby dividingthe same no.21?
Options:
(A) 21
(B) 22
(C) 23
(D) 24
(E) 25
a: Stream of consciousness: 281 + 160 = 441/21 = 21 (Remainder) The answer is (A).

question: Find the largest 4 digit number which isexactly divisible by 88?
Options:
(A) 7890
(B) 8900
(C) 9944
(D) 9976
(E) 10000
answer: Stream of consciousness: Largest 4 digit number is 9999
After doing 9999 88 we get remainder 55
Hence largest 4 digit number exactly divisible by 88 = 9999 - 55 = 9944 The answer is (C).

q: A, B, C and D enter into partnership. A subscribes 1/3 of the capital B 1/4, C 1/5 and D the rest. How much share did A get in a profit of Rs.2460?
Options:
(A) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.750
(B) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.759
(C) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.758
(D) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.752
(E) Ram = Rs.1500, Shyam = Rs.1000, Mohan = Rs.122
a: Stream of consciousness: 1/2:1/3:1/4 = 6:4:3
Ram = 6/13 * 3250 = 1500
Shyam = 4/13 * 3250 = 1000
Mohan = 3/13 * 3250 = 750 The answer is (A).

q: The speed of a boat in still water is 60kmph and the speed of the current is 30kmph. Find the speed downstream and upstream?
Options:
(A) kmph
(B) kmph
(C) kmph
(D) kmph
(E) kmph
a:
Stream of consciousness: Speed downstream = 60 + 30 = 90 kmph
Speed upstream = 60 - 30 = 30 kmph The answer is (D).
