Question
Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:
Options
A. 2 : 5
B. 3 : 5
C. 4 : 5
D. 6 : 7

Correct Answer

4 : 5

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.
		5		2
