Reasoning: Average of 20 numbers = 0
Sum of 20 numbers = (0 * 20) = 0
It is quite possible that 19 of these numbers may be positive and if their sum is a, then 20th number is (-a).
Ans: (D)

Rationale: (60/100) * 50 – (40/100) * 30
30 - 12 = 18
The answer: (A)
Question: How much 60% of 50 is greater than 40% of 30?
Options:
(A) 18
(B) 28
(C) 29

Reasoning: |8 - 9n| represents the distance between 8 and 9n on the number line. Now, the distance will be minimized when 9n, which is multiple of 9, is closest to 8. Multiple of 9 which is closest to 8 is 9 (for n = 1), so the least distance is 1: |8 - 9| = 1.
Ans: (B)
Question: If n is an integer, then the least possible value of |8 - 9n| is?
Options:
(A) 0
(B) 1
(C) 2
(D) 3
(E) 11

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) 2413
(B) 4356
(C) 9944
(D) 7939
(E) 4674

Rationale: Vowel: E O
Consonants: V R M N T
First letter can be filled in 5 Ways ( As the question states that first letter has to be a consonant)
Fifth letter can be filled in 4 Ways ( As the question states that the last letter has to be a consonant)
Now since each letter can be used only once, and 2 letters out of 7 letters are already used in First and Fifth letter
Second letter can be filled in 5 Ways
Third letter can be filled in 4 Ways
Fourth letter can be filled in 3 Ways
So, Total number of ways = 5 Ways x 5 Ways x 4 ways x 3 ways x 5 ways = 1500
The answer: (C)

Question: How many 5 letter combinations can be made from the letters of the word VERMONT if the first letter has to be a consonant and the last letter has to be a consonant, and each letter can be used only once?
Options:
(A) 21
(B) 42
(C) 1500
(D) 600
(E) 720
