A +B = 12
B +C =6 2/3
A +B +C’s total work together

Total 60 units and 1 day’s work is units
3A + 4B + 7C = 60 units
3A + 3B + 1B + 1C + 6C = 60 units
3(A + B) + 1(B + C) + 6C = 60 units
3(5) + 1(9) + 6C = 60
15 + 9 +6C = 60
6C = 60 – 24
6C = 36
C = 6
A = 2, B = 3, C = 6
A’s 1 day work = 2 units
A’s total work in how many days = 60 units
