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?
Answer & explanation
Correct answer: option 3
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
