Question

A hostel with 100 students had enough food to last them for 30 days . however , 50 new students arrived . now , for how many less days the food ?

Answer 1

100 students for 30 days

50 students add up

100+50=150 students totally

X= no of days food will

So the equation will be

100×30=150×X

3000/150

300/15

100/5

20=X

Therefore the no. of days food lasts is 20 days for 150 students.

Hope this helps you!
