A group of 15 persons spends ₹ 4,500 in 6 months, find total expenditure of a group of 25 persons in 4 months, if expenditure per person is same in both the cases.
- a.₹ 2,000
- b.₹ 3,000
- c.₹ 4,000
- d.₹ 5,000
Answer: (D) ₹ 5,000
Each person spends 4500 ÷ (15 × 6) = ₹ 50 a month. For 25 persons over 4 months the total is 25 × 4 × 50 = ₹ 5,000. The smaller amounts treat the expenditure as falling with more people.
