Q:

x and y are integers

x + y < 11 , and x > 6

What is the smallest possible value of x - y ?

A) 1	B) 24
C) 4	D) -2

Answer & Explanation Answer: C) 4

Explanation:

The smallest value will be obtained by giving x the smallest possible value while y gets the largest possible value. The smallest value for x = 7. This means that y will have to be less than or equal to 3 (so that x + y <11), but we want the largest value of y which is 3.

The difference, x - y will be 4.

Find the next number in the given number series?

50, 51, 47, 56, 40, ?

A) 58	B) 65
C) 76	D) 81

Explanation:

The given number series is 50, 51, 47, 56, 40, ?

$50 50 + 1^{2} = 51 51 - 2^{2} = 47 47 + 3^{2} = 56 56 - 4^{2} = 40 40 + 5^{2} = 65$

Hence, the next number in the given number series is 65.
