Answer 2

Step-by-step explanation:

work done by a=16days

work in 1 day =1/16part

work done by b=12days

work in 1 day=1/12part

a started work and done it for 2days.

work completed =1/16*2=1/8

work left=1-1/8=7/8

both can do work=1/16+1/12=7/48part

so time taken=7/8*7/48=49/384part

so no. of days =(1*384/49)=384/49days

hence

$7\tfrac{41}{49} days$
