Answer:

20 inmates should leave

Explanation:

A camp having 80 inmates, has food sufficient for 70 days.

total=80*70

How many inmates should leave after 10 days so that the

remaining food lasts another 80 days?

the food served for 10 days to 80 inmates

10*80

let x be inmates leave after 10 days food last for 80 days

(80-x)*80

Total=food served for 10 days+x inmates left after 10 days

80*70=10*80+(80-x)*80

70=10+80-x

x=90-70

x=20
