Answer 1

Answer:

8 days.

Step-by-step explanation:

A can finish (1/16)th portion of the work in 1 day. In 2 days he completes 1/8th portion of the work.

let us assume they work together for x days and complete the work.

(1/16 + 1/12) x= (7/8)

(7/48)x= (7/8)

x=6

Total time taken to complete the work is x+2=8 days.
