Question

A family of 6 persons spends Rs. 2700 in 15 days. For how many days, Rs. 6750 is enough for a family of 9 persons ??

Answer is...25 days

​

Answer 1

• money spent is directly proportional to : (no. of persons) × (no.of days) .

=> 2700 € (6 × 15). ------(1)

• Let the no. of days in second case be 'x'

=> 6750 € (9 × X). ------(2)

• taking the ratio of the two equations (1) & (2).

2700 (6 × 15)

=> ---------- = ------------

6750 (9 × X)

=> 2700(9 × X) = 6750(6 × 15)

=> X = (6750 × 6 × 15) / (2700 × 9)

=> X = 25 days ✓

Hope this helps you ✌️✌️☘️☘️.
