question: A printer print a page in 4 second,approx how long time it will take to print 190 page report?
Options:
(A) 12 Min 40 Sec
(B) 14 Min 40 Sec
(C) 16 Min 40 Sec
(D) 18 Min 40 Sec
(E) 11 Min 40 Sec
answer: Stream of consciousness: 1 Page = 4 Sec
30 Page = 120 Sec (2 Min)
190 Page = 12 Min 40 Sec The answer is (A).

q: A train running at the speed of 60 km/hr crosses a pole in 9 seconds. Find the length of the train?
Options:
(A) 150 meter
(B) 166 meter
(C) 154 meter
(D) 146 meter
(E) 141 meter
a: Stream of consciousness: Speed = 60*(5/18) m/sec = 50/3 m/sec
Length of Train (Distance) = Speed * Time
(50/3) * 9 = 150 meter The answer is (A).

question: An urn contains 6 red, 5 blue and 2 green marbles. If 2 marbles are picked at random, what is the probability that both are red?
Options:
(A) 6/13
(B) 5/26
(C) 6/26
(D) 9/26
(E) 10/27
answer: Stream of consciousness: Option(B) is correct
P(Both are red), 6C2/13C2 = 5/26 The answer is (B).

q: A train 400 m in length crosses a telegraph post in 16 seconds. The speed of the train is?
Options:
(A) 22 kmph
(B) 77 kmph
(C) 54 kmph
(D) 71 kmph
(E) 90 kmph
a: Stream of consciousness: S = 400/16 * 18/5 = 90 kmph The answer is (E).

question: If x<0, y<0, and |x| > |y|, which of the following must be true?
Options:
(A) x > y
(B) y^2 > x^2
(C) x^3 > y^2
(D) x < y
(E) x < y
answer: Stream of consciousness: Correct Answer: (E)
Let's go through each answer choice: (A) can never be true, since no negative is greater than a positive. (B) doesn't have to be true consider what would happen if x = -2 and y = 1. (C) can never be true, as x^3 must be negative, and y^2 must be positive. (D) can never be true, since if x < 0, -x is the same thing as |x|, and |x| > y. (E) can be manipulated by multiplying both sides by -1, which gives us x > y. Remember that x < 0, so x = |x|, and y is positive, so |y| = y. Thus x < y is the same statement as |x| > |y|, and (D) must be true. The answer is (D).

question: What is the maximum number of pieces of birthday cake of size 4" by 4" that can be cut from a cake 16" by 16"?
Options:
(A) 5
(B) 4
(C) 16
(D) 20
(E) 25
answer:
Stream of consciousness: The prompt is essentially asking for the maximum number of 4x 4 squares that can be cut from a larger 16 by 16 square. Since each 'row' and each 'column' of the larger square can be sub-divided into 4 'pieces' each, we have (4)(4) = 16 total smaller squares (at maximum). The answer is (C).
