Answer» Correct Answer - Option 3 : Rs. 28000 Given: Salary of Chirashree increased by 25% Present expenditure is Rs. 20000 Present savings is Rs. 5000 less than expenditure Concept: Total income (salary) is sum of savings and expenditure Formula: Old salary = New salary × 100/(100 + x) Where x = increment percent Calculation: Present savings = Rs. (20000 – 5000) = Rs. 15000 Present salary = Rs. (15000 + 20000) = Rs. 35000 Previous salary = 35000 × 100/125 = Rs. 28000 ∴ Previous salary of Chirashree was Rs. 28000 |
