Question

In a school hostel, a certain quantity of ration is consumed by 25 children in 30 days. However, 10 children did not return to the hostel after summer vacations. How long will the same amount of ration last now?

• A. 40 days
• B. 75 days
• C. 50 days
• D. 55 days

Answer 1

The correct option is C

50 days

Let the required number of days be x.

More number of children means ration for fewer days; so, this is inverse variation.

$\frac{25}{15}$ = $\frac{x}{30}$

x = 50 days
