Answer:
Step-by-step explanation:
An army base had provisions for 300 soldiers for 90 days. After 20 days, there should be provisions enough for 300 soldiers for another 70 days
= 21000 soldier-day
50 soldiers left so there are 300-50 = 250 soldiers left
if they consume food at the same rate, the remaining provisions will last
= 21000/250
= 84 days
