Work = 12 men × 8 days = 96 men days
In 3 days work done = 3 days × 12 men = 36 men days
Remaining work = 96 men days - 36 men days = 60 men days
Now, we have 15 men to complete work of 60 men days
60 men days × 1 / (15 men) = 4 days
Remaining work will be done in 4 days
In 3 days work done = 3 days × 12 men = 36 men days
Remaining work = 96 men days - 36 men days = 60 men days
