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
Explanation:
Let the third number be x.
Then, first number = 120% of x =$\dfrac{120x}{100}=\dfrac{6x}{5}$
Second number = 150% of x = $\dfrac{150x}{100}=\dfrac{3x}{2}$
Ratio of first two numbers = ($\dfrac{6x}{5} : \dfrac{3x}{2}$)= 12x : 15x = 4 : 5.
