Question

If Rs. 4,800 will maintain a family of 5 persons for 72 days, for how long will Rs. 6,400 maintain a family of 8 persons?

• A. 30 days
• B. 60 days
• C. 120 days
• D. None of these

Answer 1

Answer: (B)

60 days

Answer 2

1. Calculate the daily cost per person:

• If Rs. 4800 maintains 5 people for 72 days, the total cost for one person for one day is: $\frac{4800}{(5 \times 72)}$= Rs. 13.33 (approximately)

2. Calculate the total cost for 8 people:

• With 8 people, the daily cost would be $8 \times 13.33$ = Rs. 106.67 (approximately)

3. Calculate how many days Rs. 6400 will last:

• Divide the total amount of money by the daily cost for 8 people: $\frac{6400}{106.67}$ = 60 days (approximately)

Therefore, Rs. 6400 will maintain a family of 8 persons for approximately 60 days.
The correct answer is (B): 60 days
