Answer:= 1 / 4 work is completed
Step-by-step explanation: Work A can do alone = 18 days
Work B can do alone = half of A
= 9 days
(A + B ) 's 1 day work
= 1 / 16 + 1 / 8
= 1 / 16 + 2 / 16
= 1 / 8
In 3 day = 3 * 1 / 8
= 1 / 4 work is completed

Given,
A finished a work in 16 days
Now,
In 16 days = 1 work
so,
In 1 day A can finish 1/16 of a work
ATQ
B can finish 1 work in 8 days
so ,
In 1 day B can finish = 1/8. of a work
Now,
Work done by A+B together in 1 day = 1/16+1/8
= 3/16 days
so in 3/16 days = 1 work
so in 1 day A+B can finish 16/3of a work
