Two numbers A and B are, respectively, 80% and 20% more than a third number C. The ratio of the numbers A to B is:

5 : 4 4 : 5 3 : 2 3 : 4

3 : 2

Here, A and B are, respectively, 80% and 20% more than a third number C A : B : C = \(\frac{9C}{5}\) : \(\frac{6C}{5}\) : C ⇒ Ratio of the numbers A to B = \(\frac{9C}{5}\) : \(\frac{6C}{5}\) ⇒ 9C : 6C = 3 : 2.
