Correct answer: A
Concept: When income and expenses repeat unchanged every month, the saving of one month equals income minus total expenses, and this monthly saving is the same in every month. The saving accumulated over a stretch of time is that monthly saving multiplied by the number of months whose saving is actually retained; a month in which the whole saving is spent adds nothing to the accumulated amount.
Application:
Total monthly expenditure = ₹5,000 (house rent) + ₹3,000 (bills) = ₹8,000.
Monthly saving = salary − expenditure = ₹12,000 − ₹8,000 = ₹4,000.
A year has 12 months, so 12 such monthly savings of ₹4,000 each are generated.
In the birthday month the complete saving of that month, ₹4,000, is spent on the celebration, so that month retains nothing.
Number of months whose saving is retained = 12 − 1 = 11.
Savings in the year = ₹4,000 × 11 = ₹44,000.
Cross-check: Take the other route — accumulate first, then remove what was spent: a full year gives ₹4,000 × 12 = ₹48,000, and the ₹4,000 of the birthday month is spent, leaving ₹48,000 − ₹4,000 = ₹44,000. Both routes give the same figure, so the savings in the year are ₹44,000.
