Question

A military camp has provision for 63 men to least for 25 days. How many men must be transfered to another camp so that the food lasts for 30 days?

Answer 1

According to the question

$25days=foodfor63men$

$30days=x$

$30\times x=63\times 25$

$x=\frac{63\times 25}{30}$

$\approx 53men$

Hence,

$=63-52.5men$

$=10.5$

Hence 10.5 $\approx$ men must be transfered to another comp therefore the food lasts for 30 days.
