Question

60 students of a hostel had provisions for 40 days. If 20 more students were admitted, how long would the provision last?

Answer 1

Answer:

30 days

Step-by-step explanation:

students S : 60

days D : 40

and since....

S ∞ 1/D

S1 D1 = S2 D1

but ...

S2 = 60 + 20 = 80

now....

60 × 40 = 80 × D2

hence....

D2 = 30
