Options
Answer: (2) 4400
Explanation:
Total savings required in 1 year = 550 × 12 = ₹6600. First 9 months: Earning each month = ₹4000 Expense each month = ₹3500 Saving each month = 4000 − 3500 = ₹500 Total saving in 9 months = 9 × 500 = ₹4500 Remaining saving needed for last 3 months = 6600 − 4500 = ₹2100 So saving required per month (months 10–12) = 2100 ÷ 3 = ₹700 From month 10 onward expense = ₹3700, so required earning = expense + saving = 3700 + 700 = ₹4400.
