Question

200m men have provisions for 30 days if 50 men left the same provisions would last for the remaining man for how many days?

Answer 1

200 men have provisions for 30 days

So,1 men have provisions for 200*30

= 6000 days

Since 50 men leave so remaining men are 150 .

So 150 men can have provisions for 6000/150

= 40 days
