Options:
(A) 3
(B) 18
(C) 24
(D) 60
(E) None of these
answer: Stream of consciousness: In a clock, each minute makes 6

q: Find the value of y from (12)^3 x 6^4 432 = y?
Options:
(A) 2567
(B) 3589
(C) 3789
(D) 4890
(E) 5184
a: Stream of consciousness: Given Exp. = (12)3 x 64 = (12)3 x 64 = (12)2 x 62 = (72)2 = 5184
432 12 x 62 The answer is (E).

question: Which of the options is a two-digit number, which has a unit's digit that exceeds its ten's digit by 6 and the product of the given number and the sum of its digits is equal to 136.
Options:
(A) 82
(B) 93
(C) 39
(D) 28
(E) 17
answer: Stream of consciousness: Using the elimination method the option that fits this description is 17
7-1 = 3 (unit's digit that exceeds its ten's digit by 3)
17*8 = 136 (the product of the given number and the sum of its digits is equal to 175) The answer is (E).

q: Ronald and Elan are working on an assignment. Ronald takes 6 hours to type 32 pages on a computer, while Elan takes 5 hours to type 40 pages. How much time will they take, working together on two different computers to type an assignment of 110 pages?
Options:
(A) 3 hours
(B) 6 hours
(C) 4 hours
(D) 8 hours
(E) 10 hours
a: Stream of consciousness: Number of pages typed by Ronald in one hour = 32/6 = 16/3
Number of pages typed by Elan in one hour = 40/5 = 8
Number of pages typed by both in one hour = ((16/3) + 8) = 40/3
Therefore, time taken by both to type 110 pages = 110 x 3/40 = 8 hours. The answer is (D).

question: The simple interest on a sum of money is 4/9 of the principal and the number of years is equal to the rate percent. Find the rate and the time?
Options:
(A) 6 2/3%
(B) 6 2/9%
(C) 6 3/3%
(D) 9 2/3%
(E) 7 2/3%
answer: Stream of consciousness: 4/9 P = (P*R*R)/100
R = 20/3 = 6 2/3% The answer is (A).

question: Two trains run in opposite directions on a circular track. Train A travels at a rate of 4 miles per hour and Train B runs at a rate of 6 miles per hour. If the track has a radius of 6 miles and the trains both start from Point S at the same time, how long, in hours, after the trains depart will they again meet at Point S?
Options:
(A) 3
(B) 6
(C) 9
(D) 18
(E) 22
answer:
Stream of consciousness: The trains will travel the perimeter of the circle which is 12 miles. The relative speed of the trains is 2 miles per hour. Time taken to meet = 12/2 = 6 hours The answer is (B).
