Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e Rs.12,000
Let the salaries of Vipin & Dinesh be '5x' & '8x' respectively.
After the increase in salaries, the ratio becomes
⇒ (5x + 4800) / (8x + 4800) = 7 / 10
⇒ 50x + 48000 = 56x + 33600
⇒ 6x = 14400
⇒ x = 2400
Salary of Vipin will be ⇒ 5x = 5(2400)
⇒ Rs. 12,000
