The salaries of Raju and Peter are in the ratio 3 : 5. If the salary of each is increased by ₹2,500, then the new ratio is 11 : 15. What is Peter's salary?
Answer & explanation
Correct answer: option 4
Here,
Ratio of salaries of Raju and Peter = 3 : 5
Ratio after increasing both the salaries by Rs. 2500 = 11 : 15
⇒ To compare both ratios, we multiply initial with 2,
⇒ (3 : 5) x 2 = 6 : 10
⇒ 15 - 10 = 5 units = Rs. 2500
⇒ 1 unit = Rs. 500
⇒ Salary of Peter before the increase = 10 x 500 = Rs. 5000.
