Question

the monthly consumptions of milk in a hostel of 250 students in 3000 liters if 150 student leave the hotel find how much quantity of milk will be required .​

Answer 1

Answer:

1200 litres

Monthly consumption of milk if 150 students left the hostel = 1200 litres

Step-by-step explanation :

The concept based here is of unitary method.

Monthly consumption of milk of 250 students = 3000 litres

Monthly consumption of milk of 1 student = 3000/250 litres

= 300 / 25 litres

Now, if 150 students left the hostel, then ,

Total number of students after 150 have left the hostel = 250 - 150

= 100

We already know that,

Monthly consumption of milk of 1 student = 300/25 litres

Monthly consumption of milk of 100 students = 300/25 × 100

= 300 × 4

= 1200 litres

Hence,

Monthly consumption of milk if 150 students left the hostel = 1200 litres.
