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?

Answer»

Let the number of men joined be ‘x’ men

Total men = 1200

Men1200x
Time (days)3525

We know k = xy

1200 × 35 = x × 25

x = (1200×35)/25

= 1680

So, 1680 – 1200 = 480 Men

∴ 480 men should join for the same stock to last for 25 days.
