question: The number of people at Ovations Bar in the hour from 12 p.m. to 1 p.m. was 25% greater than the number of people there from 11 a.m. to 12 p.m. The number of the people at the bar from 11 a.m. to 12 p.m. was 25% less than the number there from 10 a.m. to 11 a.m. If 135 people were at the bar from 11 a.m. to 1 p.m., which of the following is the number of people in the bar from 10 a.m. to 11 a.m.?
Options:
(A) 10
(B) 20
(C) 30
(D) 40
(E) 80
answer: Stream of consciousness: No of people from 10 - 11 is x
No of people from 11 - 12 is 3x/4
No of people from 12 to 1 is (5/4)(3x/4)
Given that 3x/4 + (5/4)(3x/4) = 27x/16 = 135
Then x = 80 The answer is (E).

q: Four of the five parts numbered (a), (b), (c), (d) and (e) are exactly equal. Which of the parts is not equal to the other four? The number of that part is the answer.
Options:
(A) (2x + 3y) 2
(B) (2y x) 2 + y(16x + 5y)
(C) 4x(x + 2y) + y(4x + 9y)
(D) (2x + 2y) 2 + y(4x + 5y)
(E) (2x y) 2 + 8y(2x + y)
a: Stream of consciousness: Others are requal to 4x2 + 9y2 + 12xy. The answer is (B).

question: A wheel rotates 15 times every minute and moves 35 cm during each rotation. How many metres does the wheel move in one hour?
Options:
(A) 6 metre
(B) 12 metre
(C) 120 metre
(D) 315 metre
(E) 130 metre
answer: Stream of consciousness: Number of times wheel moves in 1 hour = 15 * 60 = 900
:. Distance moves = (900 *35) cms = 31500 cms
In metres = 315 metre The answer is (D).

q: Find the value of y from (12)^3 x 6^4 432 = y?
Options:
(A) 2234
(B) 4350
(C) 4560
(D) 5132
(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: The average marks of a Suresh in 10 papers are 80. If the highest and the lowest scores are not considered, the average is 81. If his highest score is 92, find the lowest?
Options:
(A) 55
(B) 60
(C) 62
(D) 52
(E) Cannot be determined
answer: Stream of consciousness: Total marks of 10 papers = 80 x 10 = 800
Total marks of 8 papers = 81 x 8 = 648
Total marks of two papers = (800 - 648) = 152
If highest total is 92, then the lowest total is
(152 - 92) = 60. The answer is (B).

question: The radius of a cylinder is 2 r units and height is 3 r units. Find the curved surface?
Options:
(A) 27
(B) 16
(C) 12
(D) 18
(E) 11
answer:
Stream of consciousness: 2 * * 2r * 3r = 12 r2 The answer is (C).
