Question

In a fort 600 persons have food provisions for 27 days and after 10 days 80 more persons joined them.For how many days will the same food provision be sufficient?​

Answer 1

HI FRIEND,

Answer:

Amount of food supply = 600 x 27

                                                   16200 people/days

After 10 days, the amount of food used up = 600 x 10

                                                                         =6000 people/days

16200 - 6000

              = 10200 people/days

80 more people join, lets take the days as x

680 x x = 10200

x = 10200 / 680 ( divisible by 680 )

x =15

Therefore, for 15 days the food provision will be sufficient

( HOPE THIS HELPS)
