question: Which of the options is a two-digit number, which has a unit's digit that exceeds its ten's digit by 4 and the product of the given number and the sum of its digits is equal to 208.
Options:
(A) 15
(B) 37
(C) 55
(D) 26
(E) 73
answer: Stream of consciousness: Using the elimination method the option that fits this description is 26
6-2 = 4 (unit's digit that exceeds its ten's digit by 3)
26*8 = 208 (the product of the given number and the sum of its digits is equal to 175) The answer is (D).

q: A train 250 m long, running with a speed of 50 km/hr will pass a tree in?
Options:
(A) 18sec
(B) 20sec
(C) 25sec
(D) 30sec
(E) 1min
a: Stream of consciousness: Speed = 50 * 5/18 = 125/9 m/sec
Time taken = 250 *9/125 = 18 sec The answer is (A).

question: If the average (arithmetic mean) of the four numbers K, 2K + 3, 3K 5 and 5K + 1 is 85, what is the value of K?
Options:
(A) 11
(B) 15 3/4
(C) 31
(D) 23
(E) 25 3/10
answer: Stream of consciousness: K + 2K +3 + 3K - 5 + 5K +1 = 11K -1
(11K -1)/4 = 85
11K = 85 * 4 +1 = 340 +1 = 341
K = 253 / 11 = 31. The answer is (C).

q: What is the are of an equilateral triangle of side 24 cm?
Options:
(A) 663 cm2
(B) 743 cm2
(C) 643 cm2
(D) 645 cm2
(E) 1443 cm2
a: Stream of consciousness: Area of an equilateral triangle = 3/4 S2
If S = 24, Area of triangle = 3/4 * 24 * 24 = 1443 cm2; The answer is (E).

question: In his room, Dumbo has three trousers. One of them is black, the second is blue, and the third is brown. In his room, he also has four shirts. One of them is black and the other 3 are white. He opens his room in the dark and picks out one shirt and one trouser pair without examining the colour. What is the likelihood that neither the shirt nor the trouser is black?
Options:
(A) 1/12
(B) 1/6
(C) 1/2
(D) 1/4
(E) 1/3
answer: Stream of consciousness: Probability that trouser is not black = 2/3
Probability that shirt is not black = 3/4
Required probability = 2/3 x 3/4 = 1/2 The answer is (C).

question: An amount of money is to be divided among P, Q and R in the ratio of 4 : 9 : 16. If R gets 4 times more than P, what is Q's share in it?
Options:
(A) 1,800
(B) 2,700
(C) 3,600
(D) Data inadequate
(E) None of these
answer:
Stream of consciousness: Here, neither the total amount nor the individual amount is given. So the share of Q cannot be determine The answer is (D).
