1. 6 : 5
2. 5 : 6
3. 8 : 5
4. 5 : 8

Answer 1

Correct Answer - Option 1 : 6 : 5

Given:

Two numbers A and B are respectively 80% and 50% more than the third number C.

Calculation:

Let the values of C be 100x.

A is 80% more than C.

⇒ A = 100x + 100x × 80%

⇒ A = 180x

B is 50% more than C

⇒ B = 100x + 100x × 50%

⇒ B = 150x

Ratio of A : B = 180x : 150x

⇒ 6 : 5

∴ The ratio of A and B is 6 : 5.
