Hi,

16 men to build a wall 80 metres long in 10days ⇒ 8m/day 0r 64m in 8days

80-64 = 16, 16+10 = 26m must be built in 2 days. 

@man can build 1/2m per day or 1m in 2 days.

Would take 26 men working 2 days for the 26m needed. 

 more men must be engaged to complete the work within the agreed time
