q: Two numbers are in the ratio 3 : 4. If the sum of numbers is 63, find the numbers.
Options:
(A) 26,37
(B) 25,38
(C) 27,36
(D) 28,35
(E) 29,34
a: Stream of consciousness: Sum of the terms of the ratio = 3 + 4 = 7
Sum of numbers = 63
Therefore, first number = 3/7 63 = 27
Second number = 4/7 63 = 36
Therefore, the two numbers are 27 and 36. The answer is (C).

question: A train 650 m long is running at a speed of 81 km/hr. In what time will it pass a bridge 340 m long?
Options:
(A) 42
(B) 43
(C) 44
(D) 45
(E) 46
answer: Stream of consciousness: Speed = 81 * 5/18 = 45/2 m/sec
Total distance covered = 650 + 340 = 990 m
Required time = 990 * 2/45 = 44 se The answer is (C).

q: The average of seven results is 156 and that of the first six is 169. The fifth result is?
Options:
(A) 120
(B) 160
(C) 89
(D) 78
(E) 148
a: Stream of consciousness: 7 * 156 6 * 169 = 78 The answer is (D).

question: If 10 crates have 95 apples each and how many apples more is required in order to make 100 apples in each crate?
Options:
(A) 5
(B) 10
(C) 15
(D) 50
(E) 0
answer: Stream of consciousness: Each crate requires 5 apples and totally there are 10 crates so required apples = 10 * 5 = 50 The answer is (D).

q: What approximate value should come in place of the question mark (?) in the following equation?
16524 + 1492 - 250.0521?
Options:
(A) 1600
(B) 1800
(C) 1900
(D) 2400
(E) 1400
a: Stream of consciousness: ? 16 23 + 1490 250 1600 The answer is (A).

q: Two trains are moving at 75 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) 6 6/29 sec
(B) 7 1/7 sec
(C) 7 2/2 sec
(D) 8 1/2 sec
(E) 7 1/19 sec
a:
Stream of consciousness: 70 + 75 = 145 * 5/18 = 725/18 mps
D = 150 + 100 = 250 m
T = 250 * 18/725 = 180/29 = 6 6/29 sec The answer is (A).
