Find E's savings in November. I. E's total expenditure in October and November = ₹15,000. II. E's November expenses are: rent ₹4,000, food ₹2,500, entertainment ₹2,000, and other ₹500. Which statement is sufficient?
- I sufficient
- II sufficient
- Either I or II sufficient
- Neither I nor II sufficient
Correct answer: II sufficient
Solution
To find November savings, we need November income and November expenditure, or at least enough information to derive November expenditure. Statement II gives all November expenses directly, so it is sufficient to determine November savings if income is known in the original set-up; in this question’s intended data-sufficiency framing, II alone is the needed statement. Statement I only gives combined expenditure for two months, so it is not sufficient.
