A+B=12
B+C=20

frist we find the One day work,
By taking LCM,
60

B+C=3
A+B=5

They working together:
A+B+B+C=8
A+B+C=4 .............(1)

now,

we know the value of A+B frist day put it in (1)
5+c=4 hence C=1
C work together for 4 days so 1X4=4 unit per day C works.
total unit work 60.
60 - 4=56
A+B=5
the remaining work 56 unit will finished by A+B in 56/5 days i.e 11.2 days
