Options:
(A) 85
(B) 89
(C) 92
(D) 98
(E) 100
a: Stream of consciousness: Ordering the data from least to greatest, we get:

The median score is 92. The answer is (C).

question: Solve:-
555 x 555 x 555 + 555 x 555 x 555 = ?(555 x 555 - 555 x 555 + 555 x 555)
Options:
(A) 888
(B) 333
(C) 555
(D) 988
(E) 1110
answer: Stream of consciousness: Given Exp. = (a3 + b3) = (a + b) = (555 + 555) = 1110(a2 - ab + b2) The answer is (E).

q: How much is 80% of 40 is greater than 4/5 of 25?
Options:
(A) 22
(B) 77
(C) 15
(D) 12
(E) 88
a: Stream of consciousness: (80/100) * 40 (4/5) * 25
32 - 20 = 12 The answer is (D).

question: How many Numbers can be formed with digits 2,4,6,8 without repetition?
Options:
(A) 124
(B) 256
(C) 64
(D) 84
(E) 94
answer: Stream of consciousness: Number of one digit numbers = 4
Number of two digit numbers = 4 P 2 = 12
Number of Three digit numbers = 4 P 3 = 24
Number of four digit numbers = 4 P 4 = 24
So, total = 24 + 24 + 12 + 4 = 64 The answer is (C).

q: A man, a woman and a boy can complete a job in 3, 4 and 12 days respectively. How many boys must assist 1 man and 1 woman to complete the job in 1/4 of a day?
Options:
(A) 22
(B) 77
(C) 26
(D) 41
(E) 66
a: Stream of consciousness: (1 man + 1 woman)'s 1 day work = (1/3 + 1/4) = 7/12 Work done by 1 man and 1 woman in 1/4 day = (7/12 * 1/4) = 7/48
Remaining work = (1 - 7/48) = 41/48
Work done by 1 boy in 1/4 day = ( 1/12 * 1/4) = 1/48
Number of boys required = 41/48 * 41 = 41. The answer is (D).

q: A train 250 m long running at 72 kmph crosses a platform in 50 sec. What is the length of the platform?

(B) 200m
(C) 250m
(D) 750m
(E) 300 m
a:
Stream of consciousness: D = 72 * 5/18 = 50 = 1000 250 = 750m The answer is (D).
