A and B's salaries together amount to Rs. 2,000. A spends 95% of his salary and B spends 85% of his. If now their savings are the same, what is A's salary?
Correct answer: D. Rs.1500
- A. Rs.500
- B. Rs.750
- C. Rs.1250
- D. Rs.1500
Explanation
A saves 5% of A's salary, while B saves 15% of B's salary. Equal savings give 0.05A = 0.15B, so A = 3B; with A + B = 2000 rupees, 4B = 2000 rupees and A = 1500 rupees. The likely mistake is comparing spending percentages rather than saving percentages and choosing 1250 rupees.
