12 days.
work done by A in 1 day = 1/8.
for 2 days its 1/4.
remaining work is 1-1/4=3/4.
25 % of work is done atlast be C.
thrfore it is 1/4.
work done by B = 3/4-1/4 = 1/2.
days for B to complete is (1/2) /(1/12) = 6
days for C to complete 1/4 of the job (1/4) /(1/16) = 4.
A takes 2 days , B takes 6 days and C takes 4 days.
total is 12 days.

Answer / himanshu
Que is in how many days total work is completed
A. 8day
B. 12 day
C. 16 day
Total work 48
A. 6 unit per day
B. 4 unit per day
C. 3 unit per day
A works for 2 day =12
B works untill 25% of work completed so 48×25%=12 and that mean C works for 12
So A +C = 12+12=24
SO
Remaining is 24
B =24/4 =6
So at last A work for 2 day B work for 6 day and C works for 4 Day total 12 days
