- If 20 men can build a wall 66 metres long in 6 days,
length of a similar wall that can be built by 86 men in 8 days = (66*86*8)/(6*20) = 11*172/5 = 1892/5 mtrs = 378.4 mtrs - 11 years agoHelpfull: Yes(29) No(2)
- 378.4 metres.

- In 1 day , 1 men can do work i metres = 66/(6*20)
so 8 day , 86 men can do work = (66*86*8)/(6*20) in meter
answer = 1932*100/5 (in cm)
= 38640 (in cm)
= 386.4 (in m) - 11 years agoHelpfull: Yes(7) No(14)
- 20:86 , 6:8 :: 66:x
hence x=(66*86*8)/(20*6)= 378.4 m - 11 years agoHelpfull: Yes(5) No(3)
- 86*8*60/20*6=344
