Answer 1

Answer :  

we are given that for 15 men provision lasted for 3 days .

To find : no of men for whom provision will last for 45 days .

let no. of men be ' $x$ ' .

then,  we have ,

provision = total no. of men x total no . of days

$45 x = 30\times 15$

$x = \frac{450}{45}$

$x = 10$

hence , for  10 men provision will last for 45 days.

Answer 2

Given: For 15 men the provision will last for 30 days.

We have to find for how many men the same provision will last for 45 days.

This problem is solved in the following way

Let assume the number of men be $x$

we have,

provision = total number of men * total number of days

$=>45*x=15*30\\=>45x=450\\=>x=\frac{450}{45} \\\\=>x=10$

So, for 10 men the same provision will last for 45 days.​
