Given:
P does the work in 24 days
Q does the work in 16 days
R does the work in 12 days
Solution:
Total work = LCM of 24, 16, 12 = 48 unit
Work done by A in 1 day = 48/24 = 2 unit
Work done by B in 1 day = 48/16 = 3 unit
Work done by C in 1 day = 48/12 = 4 unit
They together will compete the work = 48/(2+3+4) = 48/9= days
