Given that A and B can finish a work in 16 days and 12 days respectively.
Work-done by A in 1 - day = 1/16.
Work-done by B in 1 - day = 1/12.
A started the work and worked at it for 2 days.
Work done by A in 2 days = 1/16 * 2
= 1/8.
Remaining work = 1 - 1/8
= 7/8.
(A + B)'s 1 - day work = (1/16 + 1/12)
= 7/48.
Then A and B will do 7/8 th part of work = 48/7 * 7/8
= 6 days.
Therefore the total time taken to complete the work = 2 + 6
= 8 days.
Hope this helps!
