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

• it can be solved by counting manday
  56 meter wall is made = 20 x 6 = 120 mandays
  120 mandays made a wall = 56 meter
  1 mandays made a wall = 56/120 meter
  (35 x 3) mandays made a wall = (56/120) x (35 x 3) = 49 meter (answer)
