If 20 men can build a wall of 56 m long in 6 days, what length of a similar wall can be built by 35 men in 3 days?

47m 48m 49m 50m

49m

According to the question: \(\frac{\text{20 x 6} }{56 }\) = \(\frac{\text{35 x 3} }{Length }\) \(\frac{\text{120} }{56 }\) = \(\frac{\text{105} }{Length }\) Length = 49 m Thus, we can say that the length of the wall = 49 m
