Question

two numbers are respectively 20% and 50% more than a third number.find the ratio of first 2 numbers?

Answer 1

let the third number be 100
first number = 20% of 100 + 100 = 120
second number = 50%of 100 + 100 = 150
120:150
4:5

Answer 2

Let the third number be x.

First Number (120/100)*x = 6x/5

Second Number (150/100)*x = 3x/2

Ratio = 6x/5:3x/2

=>4:5
