Question
The salaries of A and B are in the ratio 3:5. If the
salary of A increases by 20% and the salary of B increases by 10%, the new sum of their salaries becomes 49140. What is A's original salary?Solution
Let the original salaries of A and B be 3x and 5x, respectively. After the increment, A's salary = 3x × 1.2 = 3.6x. B's salary = 5x × 1.1 = 5.5x. According to the question 3.6x + 5.5x = 49140 Solving for x: x = 49140/9.1 x = ₹5,400. A's original salary = 3x = ₹16,200. Thus, the correct answer is ₹16,200 . Ans. d
