Step-by-step explanation:
Let a be the extra number of men employed to complete the work in 7 days
Number of men 294 a
days 9 7
As we know,
the number of men hired and the time required to finish the piece of work are inversely proportional.
Therefore,
294 × 9 = a × 7
2646/7 = a
378 =a
Thefefore, the number of extra men required to complete the job in 7 days = 378-294
= 84
