"30",
"20",
"32",
"18"
] | A | I simply looked at the 3 different possible scores for each individual test: 18,32,26
We have to find the minimum range:
32-18=14
32-26=6
26-18=8
The find the minimum range, you have to make the set of the 5 scores as small as possible.
Which means that 4 of the 5 scores of each individual person is zero.

Rahul's Mathematics test had 85 problems, 10 arithmetic, 30 algebra, 35 geometry problems.
Although he answered 70% of arithmetic, 40% of arithmetic and 60% of geometry problems correctly,
still he got less than 60% problems right. How many more questions he would have to answer more to get
passed | [
"11",
"7",
"5",
"8"
] | A | Explanation:
Number of questions attempted correctly = (70% of 10 + 40% of 30 + 60% of 35)
= 7 + 12 + 21 = 40.
Questions to be answered correctly for 60% = 60% of total quations

He would have to answer 51 - 40 = 11

A team of 8 persons joins in a shooting competition. The best marksman scored 85 points. If he had scored 92 points, the average score for the team would have been 84. The number of points, the team scored was | [
"665",
"287",
"127",
"227"
] | A | Let the total score be x.
(x + 92 - 85) / 8 = 84.
So, x + 7 = 672 => x = 665.

If the quantity 8^2+ 8^4 + 8^6 is written as (a + b)(a – b), in which both a and b are integers, which of the following could be the value of b? | [
"37",
"29",
"64",
"49"
] | C | (a+b)(a-b) = a^2 - b^2
8^2+ 8^4 + 8^6 = 8^2 (1+8^2+8^4)
if the above expression is solved even then every term of the expression will remain a multiple of 8^2 which is out of parenthesis
hence, b must be a multiple of 8^2 i.e. 64

In a game of billiards, A can give B 10 points in 50 and he can give C 30 points in 50. How many points can B give C in a game of 100? | [
"50",
"70",
"60",
"75"
] | A | A scores 50 while B score 40 and C scores 20.
The number of points that C scores when B scores 100 = (100 * 20)/40 = 50.
In a game of 100 points, B gives (100 - 50) = 50 points to C
