Question

8. There are 75 students in a hostel . Food provision for them is for 20 days . How long will these provisions last , if 50 more students join the group ?​

Answer 1

Step-by-step explanation:

The given problem is in inverse proportion

The increase in one means decrease in other

here x1=75

y1=20

x2=75+50=125

y2=?

now if the data is in inverse proportion

x1×y1=x2×y2

75×20=125×y2

y2=1500÷125

y2=12

So, if there is an increase of 50 students, the food provision will last long for 12 days
