In a camp of 70 boys, there are food provisions for 36 days. If 50 more boys join the camp, then how many days will the provisions last?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 21 days.
According to the given question,
M1 × D1 = M2 × D2
⇒ 70 × 36 = (70 + 50) × D2
⇒ D2 = 70 × 36/120
⇒ D2 = 21 days
