Options:
(A) 7/98
(B) 1/70
(C) 1/98
(D) 1/96
(E) 1/68
answer: Stream of consciousness: 2/5 * 6/7 * 1/3 * 1/8 = 12/840 = 1/70 The answer is (B).

q: If rupee one produces rupees nine over a period of 40 years, find the rate of simple interest?
Options:
(A) 22 1/8 %
(B) 22 3/2 %
(C) 28 1/2 %
(D) 22 1/2 %
(E) 32 1/2 %
a: Stream of consciousness: 9 = (1*40*R)/100
R = 22 1/2 % The answer is (D).

question: Eddy and Freddy start simultaneously from city A and they travel to City B and City C respectively. Eddy takes 3 hours and Freddy takes 4 hours to complete the journey. If the distance between City A and City B is 480 kms and City A and City C is 300 kms. What is the ratio of their average speed of travel? (Eddy: Freddy)
Options:
(A) 32/15
(B) 3/8
(C) 8/5
(D) 5/8
(E) 5/3
answer: Stream of consciousness: Distance traveled by Eddy = 480 km
Time taken by Eddy = 3 hours
Average speed of Eddy = 480/3 = 160 km/hour
Distance traveled by Freddy = 300 km
Time taken by Freddy = 4 hours
Average speed of Freddy = 300/4 = 75 km/hour
Ratio of average speed of Eddy to Freddy = 160/75 = 32/15 The answer is (A).

(D) Rs.55.33
(E) None of the above
a: Stream of consciousness: 50*10 = 500

840/15 = 56 The answer is (C).

question: In Badminton game, one player throws two fair, six-sided die at the same time. If the player receives at least a five or a one on either die, that player wins. What is the probability that a player wins after playing the game once?
Options:
(A) 1/3
(B) 4/9
(C) 5/9
(D) 2/3
(E) 3/4
answer: Stream of consciousness: In Badminton game, Probably the easiest approach would be to find the probability of the opposite event and subtract it from 1:
P(win) = 1- P(not win) = 1 - 4/6*4/6 = 5/9. The answer is (C).

question: What least number must be added to the least number of six digits so that the resulting number may be a perfect square.
Options:
(A) 489
(B) 267
(C) 278
(D) 199
(E) 111
answer:
Stream of consciousness: The least number of six digits = 100000 3 10 00 00 317 9 61 100 61 627 3900 4389 489 Least number to be added = 489. The answer is (A).
