Answer 2

20 days

Step-by-step explanation:

Best way to solve it is using work time formula which is

(hour*days) =work

Let,x be the no. of days required to complete the work if the man works 8 hours per day

10*16=k

8*x=k

Since both the equations equate to same value

10*16=8*x

Solve this and the answer is 20
