In a hostel, there are 120 students and food stock is for 45 days. If 30 new students join the hostel, in how many days will the complete stock be exhausted?


A) 38

B) 40

C) 32

D) 36

Correct Answer:
D) 36

Description for Correct answer:

Let food stock will be exhausted in x days.

Given, M1 = 120

D1 = 45

M2 = 120 + 30 = 150

D2 = X

Then, using M1D1= M2D2

120 x 45 = 150 x x

X = \( \Large\frac{120 \times 45}{150} = 36 \)
