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

2 : 5

3 : 5

4 : 5

6 : 7

Answer : Option C

Explanation :

Let the third number be x.

Then, first number = 120% of x = $\frac { 120 X } { 100 }$ = $\frac { 6 X } { 5 }$

Second number = 150% of x = $\frac { 150 X } { 100 }$ = $\frac { 3X } { 2}$

Ratio of first two numbers =[ $\frac { 6 X } { 5 }$ : $\frac { 3X } { 2}$ ] = 12x : 15x = 4 : 5
