Question

20 men can do a work of wall 66m in 6 days then 86 men working for 8 days build how many meters

Answer 1

Hi,

So first we have to find height of wall in meters,

(1) More Men : More Meter

(2) More Days : More Meter

So,

:• 20 : 86 = 66 : X

:• 6 : 8 = 66 : X

:• X = ( 86 × 8 × 66) / ( 20 × 6 )

:• X = 378.4 m

So the height of wall can be made in 8 days by 86 men is 378.4 m.

Hope it helps. THANK YOU.
