At a refugee camp, the food supplies were enough to feed 300 refugees for 45 days. But 60 more refugees joined after 15 days. For how many days would the rest of the food supplies last?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 25 days.
Formula used:
(Men × Days × Hours)/Work
Calculations:
(Men1 × Days1) = (Men2 × Days2) + (Men3 × Days3)
⇒ (300 × 45) = (300 × 15) + (360 × Days3)
⇒ 13500 = 4500 + 360 × Days3
⇒ 9000 = 360 × Days3
⇒ Days3 = 25 days
