A fort has provision for 50 days. After 15 days a reinforcement of 150 men arrives and the provision now lasts 25 days. How many men were there in the fort?

Validate

Solution:

Days	Men
35	x
25	x+150

⇒

{x+150}/{x}

{35}/{25}

⇒

1 + {150}/x

{35}/{25}

⇒

{150}/x

{10}/{25}

∴ x =

{25}/{10} × 150

= 375
Number of men in the fort=375
