Question

Q2. There are 100 students in a hostel. Food provision for them is for 20 days. How
long will these provisions last, if 25 more students join the group?​

Answer 1

Answer:

Step-by-step explanation:Number of person = 100, Number of days = 20,

                       = 100 x 20

Number of person = 125      (∵ 25 student join), let Number of days = x

                       = 125 x X

So,      100 x 20 = 125 x X

or        2000 = 125x

or,          125x =  2000

∴        X = space space space space space space space space space 2000 over 125 = 16

 

Therefore,   that the last provisions will 16 days
