Answer:
let a complete x work so work done in 1 day =1/x
as b works twice as fast as a so work done by b in i day=1/2x
b completes a task in 12 days
so in 1 day b does 1/2x work
1/2x=12
x=1/24
a will do 1/12 work in 12 days
work done by them together=1/24+1/12=1/8
thus they both can complete the work in 8 days.
