Question

Ration is available for 75 students on a hostel for 20days how long it last for the remaining students if 25 students left the hostel after 10days

Answer 1

Answer:

15 days.

Step-by-step explanation:

The total ration for the 75 students is given as = 75 × 20 = 1500

After 10 days the amount of ration consumed is = 10 × 75 = 750

The remaining ration = 1500 - 750= 750

The remaining students = 75 - 25 = 50

We need how many days the amount 750 will last the remaining 50 students.

We get this by :

750/50 = 15

The remaining amount ration will last the remaining students 15 days.

Answer 2

Answer:

( 75 * 10 ) / 50 = 15

So the remaining amount of ration will last the remaining students for 15 days.

Step-by-step explanation:

Ration is consumed by 75 students for ( 20 - 10 ) = 10 days.

After 10 days 25 students left their hostel. Now the total number of students are ( 75 - 25 ) = 50 students.

 

Ration is consumed by 75 students for 10 days

Now ration is consumed by 75 students for ( 75 * 10 ) / 50 = 15 days

so the answer is 15 days.
