Best answer
Correct Answer - Option 3 : Rs. 1,44,000

Given:

Salaries of Ravi and Ankit are in the ratio 5 : 7

The salary of each is increased by Rs. 6000

Calculation:

Let the original salaries of Ravi and Ankit be Rs. 5x and 7x respectively.

Then,

⇒  (5x + 6000)/(7x + 6000) = 11/15

⇒ 15(5x + 6000) = 11(7x + 6000)

⇒ 75x + 90000 = 77x + 66000

⇒ 2x = 24000

⇒ x = 12000

Total salary of Ravi and Ankit = 5x + 7x

⇒ 5 × 12000 + 7 × 12000

⇒ Rs. 1,44,000

∴ The sum of salary of Ravi and Ankit is Rs. 1,44,000.
