Answer 2

80

Step-by-step explanation:

total no. of work in units = 80*30 =2400 units.

20% of work done in 10 days = 480 units of work done in 10 days.

means, daily 48 (480/10) units of work done by 80 people.

so, their efficiency = 48/80 =3/5.

Required units of work 2400-480 = 1920 units.

1920 units should be done in 20 days to complete work with in time .

means, daily 96 units of work should done.

• so, 96 units done with 3/5 efficiency (96/(3/5) ) 160 people required.

already, 80 people working so, 80 more required to complete the work within time..
