If A exceed B by 50% and B is less than C by 60%, then the ratio of A to C is:1. 4: 52. 5: 73. 3: 54. 7: 9

Answer» Correct Answer - Option 3 : 3: 5

Given that:

A is 50% greater than B

and B is 60% less than C

Hint:

  • x% of 100 = x and
  • less or more is always from 100%

∴ 60% less than C = (100 - 60) % of C = 40% of C

Calculations:

Let B = 100

∴ A = 50% greater then B

⇒ A = 100 + 50 = 150

∴ B = 60% less then C = 40% of C

⇒ 100 = (40/100) × C

⇒ C = (100 × 100)/40

 ⇒ C = 250

∴ ratio of A to C is 150: 250

 ⇒A: C = 3: 5
