Question

There are 90 students in a hostel. Food provision for them is for 20 days. How long will their food

provision last if 30 more students join the group?​

Answer 1

Answer:

The provisions will last for 15 days.

Step-by-step explanation:

For 90 students, the provisions last for 20 days.

∴ for 1 student, the provisions will last for (20 × 90) = 1800 days.

∴ for (90 + 30) = 120 students, the provisions will last for 1800/120

= 15 days.

Answer 2

Answer:

The answer will be 15

Step-by-step explanation:

Food provision of 90 students -- 20 days

Foos provision of 1 student will be -- 20×90

(Now as 30 students more has been added there is 120 students in total) so..

Food provision of 120 students will be --- 20×90/120 = 15
