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.
