Bilal spends 45% of his monthly income on household items, 25% of his monthly income on buying cloths, 7.5% of his monthly income on medicines and saves the remaining amount which is Rs. 9000. Find his monthly income.
Correct answer: A. Rs. 40000
- A. Rs. 40000
- B. Rs. 36000
- C. Rs. 50000
- D. Rs. 45000
- E. None of these
Explanation
Total spending is 45% + 25% + 7.5% = 77.5%, so the saved amount is 22.5% of monthly income. Therefore, 22.5% of income = Rs. 9000, and income = Rs. 9000 ÷ 0.225 = Rs. 40000. The likely trap is Rs. 36000, which uses an incorrect saving percentage.
