a=20
b=30
c=60
lcm=60
efficiency : a=3 b=2 c=1
1st day A =3 unit
2nd day A =3unit
3rd day A+B+C=3+2+1=6unit
means in 3 days 3+3+6=12unit work is completed
so 60(12+5) unit in 15 (3×5)days ...
b=30
c=60
lcm=60
efficiency : a=3 b=2 c=1
1st day A =3 unit
2nd day A =3unit
3rd day A+B+C=3+2+1=6unit
means in 3 days 3+3+6=12unit work is completed
so 60(12+5) unit in 15 (3×5)days ...
