answer- The work is completed in 142 days
C works for 24 days
Number of days in which A can do work = 36 (Given)
Number of days in which B can do work = 54 (Given)
Number of days in which C can do work = 72 (Given)
Let the work be completed in = x days.
Let C work for = x days
Then A will work for = (x - 8) days and B will works for = (x - 12) days.
Thus, according to the question,
[ (x−8)/36 (x−12)/ 54+x/72] = 1
13x = 312
x = 312/13
x = 24
Therefore, the number of days for which C worked was 24.
lakshmi=8day = 48 unit
raji = 4day= 48 unit
so, 216+96 = 312
sujata= 312/3= 104
