Question

There are 10 boys in a hostel. They have food to last for 15 dass 10 more boys
joined the hostel. For how long the same food will last now?​

Answer 1

Answer:

7 and half days

Step-by-step explanation:

10 boys have food for 15 days

If another 10 boys join the hostel, they have to share their food, the food becomes half the initial food

Thus the days will also be halved

Thus the food will last for half the initial day

X food = 15 days

X/2 food = 15/2 days = 7.5 days
