1200 men can finish a stock of food in 35 days. How many more men should join them so that the same stock may last for 25 days?

Explanation

Let `x` be the number of men required to finish the stock in `25` days.
Since, the number of men and the time taken to finish a stock are in inverse variation, we have:
`=> 1200xx35=25x`
`=> x= (1200xx35)/25`
`=> x=1680`
`therefore` Required number of men` =1680−1200=480`
`therefore` An additional `480` men should join the existing `1200` men to finish the stock in `25` days.
