1/4 = 1/12 + 1/18 + 1/c
c = 9 days
take total work as 1
work done by a in one day =( total work/total number of days taken) = 1/a = 1/12.
similarly work done by b and c are 1/b = 1/18 and 1/c respectively.
total work done by all three in one day = 1/12 + 1/18 + 1/c
(work done in one day × total number of days = total work )
[1/12 + 1/18 + 1/c] ×4 = 1
1/4 = 1/12 + 1/18 + 1/c
c = 9 days
c = 9 days
