Q1: 

Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:

A. 2 : 5 B. 3 : 5 C. 4 : 5 D. 6 : 7

Answer: Option C

Explanation:

Let the third number be x.

Then, first number = 120% of x =	120x	=	6x
	100		5

Second number = 150% of x =	150x	=	3x
	100		2

Ratio of first two numbers =		6x	:	3x		= 12x : 15x = 4 : 5.
