In an army camp, there were provisions for 550 men for 28 days. But, 700 men attended the camp. How long did the provisions last?
Number of days the provisions will last for 550 men = 28 days
Therefore, total amount of food available =550×28 units
No. of men attended = 700
Let the no. of days now food lasts =x
Therefore, total amount of food now available =700×x
∴550×28=700×x
⇒x=550×28700=22 days
