Question: 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.
