Answer:
7 people
Step-by-step explanation:
Work done by 1 person in a day = 1/160
Work done by 8 people in 5 days = 40 / 160
Work left = 120 / 160
Time to be taken to complete the remaining work = 8 days
No. of people needed = 120 / 160 × 160 × 1/8
= 15
People needed more = 15 - 8 = 7 people
Hope it helps.
