In a school for midday meal food is sufficient for 250 students for 33 days, if each student is given 125 gm meals. 80 more students joined the school. If same amount of meal is given to each student, then the food will last for

20 days

40 days

30 days

25 days

Explanation:

M₁ = 250, D ₁ = 33 days
per day meal W₁ = W₂ = 125 g
M₂ = (250 + 80) =330 and D₂=?
According to the formula
M₁D₁W₂ = M₂D₂W₁
250 x 33 x 125 = 330 x D₂x 125
⇒ D₂ = (250 x 33)/330
∴ D₂ = 25 days
