Reasoning: Increase = (10/50)*100 = (1/5)*100 = 20%.
Ans: (E)
Question: John makes $50 a week from his job. He earns a raise and now makes $60 a week. What is the % increase?
Options:
(A) 16%
(B) 16.66%
(C) 17.9%
(D) 18.12%
(E) 20%
Rationale: Using the elimination method the option that fits this description is 25
5-2 = 3 (unit's digit that exceeds its ten's digit by 3)
25*7 = 175 (the product of the given number and the sum of its digits is equal to 175)
The answer: (A)
Question: Which of the options is a two-digit number, which has a unit's digit that exceeds its ten's digit by 3 and the product of the given number and the sum of its digits is equal to 175.
Options:
(A) 25
(B) 36
(C) 47
(D) 52
(E) 63
Reasoning: (45/100) * 60 – (35/100) * 40
27 - 14 = 13
Ans: (B)
Question: How much 45% of 60 is greater than 35% of 40?
Options:
(A) 18
(B) 13
(C) 15
(D) 17
(E) 71
Rationale: Largest 4 digit number is 9999
After doing 9999 ÷ 88 we get remainder 55
Hence largest 4 digit number exactly divisible by 88 = 9999 - 55 = 9944
The answer: (C)
Question: Find the largest 4 digit number which isexactly divisible by 88?
Options:
(A) 5678
(B) 7654
(C) 9944
(D) 9950
(E) 10000
Reasoning: 20 + 24 + 8 * 2 = 60/2 = 30
Ans: (A)
Question: The average age of 8 men increases by 2 years when two women are included in place of two men of ages 20 and 24 years. Find the average age of the women?
Options:
(A) 30
(B) 35
(C) 32
(D) 40
(E) 46
Reasoning: Using Speed Formula: Speed = Distance / Time
Distance to be covered = 51-11 = 40
Speed of approach = 57 + 63 floors/min
Time = 40/120 = 1/3
So Steve will cover 57x 1/3 floors in that time = 19
So he will be in 19 + 11 floor = 30th Floor
Ans: (C)

Question: Steve gets on the elevator at the 11th floor of a building and rides up at a rate of 57 floors per minute. At the same time Joyce gets on an elevator on the 51st floor of the same building and rides down at a rate of 63 floors per minute. If they continue traveling at these rates, at which floor will their paths cross?
Options:
(A) 19
(B) 28
(C) 30
(D) 32
(E) 44
