1. 8 ∶ 14 ∶ 23
2. 10 ∶ 13 ∶ 16
3. 9 ∶ 15 ∶ 19
4. 14 ∶ 17 ∶ 19

Answer 1

Correct Answer - Option 1 : 8 ∶ 14 ∶ 23

Given:

Three numbers are 60% and 180% and 360%

Calculations:

Let the fourth number = x

According to the question,

First number = x + x × (60/100) = 1.60x

Second number = x + x × (180/100) = 2.80x

Third number = x + x × (360/100) = 4.60x

So, the ratio of first, second and third number = 1.60x ∶ 2.80x ∶ 4.60x = 8 ∶ 14 ∶ 23

∴ The ratio of first, second and third number is 8 ∶ 14 ∶ 23
