Answer 2

Answer: 40 Days

Step-by-step explanation:  

Let total work done be 120*25 = 3000 units work

So, 120 workers can do 120 units of work per day

So, 1 worker can do 1 unit of work per day

From here, 120 workers did 1200 units of work in 10 days. Remaining work = 3000-1200 = 1800 (10 days spent here)..........(1)

After 10 days, 30 workers left, So 90 remaining workers did 900 units of work in 10 days. Remaining work = 1800-900 = 900 (10 days spent here)..........(2)

After further 10 days, 30 more workers left, So remaining 60 workers did 600 units of work in 10 days. Remaining work = 900-600 = 300 (10 days spent here).............(3)

Now, 30 more workers left, so remaining 30 workers did 300 units of work in 10 days. Remaining work = 300-300 = 0 (10 days spent here)........(4)

Upto statement (4), all work is performed as per given condition. So, Work completed in 10+10+10+10 = 40 days
