Question

In a camp there is a food stock for 500 members for 70 days. If 200 more joined in the camp then for how many days the food stock is sufficient ? 

A) 50 

B) 60 

C) 70

D) 90

Answer 1

Correct option is (A) 50

Food stock = 500 \(\times\) 70 = 35000

Let after 200 more joined the camp the food stock is sufficient for x many days.

\(\therefore\) x (500+200) = 500 \(\times\) 70

\(\Rightarrow\) \(x=\frac{500\times70}{700}=50\)

\(\therefore\) Food is sufficient for 50 days after 200 more joined in the camp.
