Question

In a fort there were provisions for 45 days for 150 men. After 10 days 25 men left over . The food would now last long for ?

Answer 1

150 men : 45 days

After 10 days,

150 men : 35 days

And now, 25 men left.

Therefore, 125 men : How many days?

150 : 125 :: x : 35

150 x 35 = 125x

x = 150 x 35/125

x = 42

Therefore it will last for 42 days.
