Question

. Eight men can build a bridge in 12 days. Find the time taken for 6 men to build the same bridge. State the assumption made.
​

Answer 1

the two people who left were the key design and safety engineers and they left because they couldn't agree with the incompetent manager/lead on the project to ignore their critical actions.

Now the remaining 6 people cannot build the bridge at all in 12 days and after a failure, the manager gets fired, luckily no one dies, project is waiting for new funding and hiring new manager and engineers and after 2 years it is finally done.
