Answer» Correct Answer - Option 1 : 48 Given: The ratio of two numbers = 3 ∶ 5 Calculation: Let the two number be 3x and 5x respectively Now, A/Q (3x + 12)/(5x + 12) = 5/7 ⇒ 7(3x + 12) = 5(5x + 12) ⇒ 21x + 84 = 25x + 60 ⇒ 25x – 21x = 84 – 60 ⇒ 4x = 24 ⇒ x = 6 The numbers are 18 and 30 Sum = 18 + 30 = 48 ∴ The sum of the given number is 48 |
