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

• in case 1
  no of men =20,length of wall =56 in 6 days
  in case 2:
  let the length of wall be x
  by comapring both cases 1 and 2
  56/(20*6)=x/(35*3)
  x=49.

• for 56m==>20*6=120
  so, for 35*3=105==>??=======>56*105/120==>49m

• by applying the formula ,
  
  M1 * D1 / W1 = M2 * D2 / W2
  
  M-> MEN , D-> DAY , W-> WORK
  
  therefore,
  
  20 * 6 / 56 = 35 * 3 / W2
  
  120 / 56 = 105 / W2
  
  answer -> W2 = 49.

• 20 men ----56m----6 days
  1 men ---- 56/20 m----6/20
  35 men----56*35/20m -----6*35/20
  
  
  now,
  
  6*35/20 men-----56*35/20
  3 men------(56*35*20*3)/(20*6*35) = 28

• 20Men-56m-6days
  35Men-? m -3days
  ?=(35/20)*(3/6)*56
  ?=49m

• Ans-49
  M1D1/W1 =M2D2/W2(FORMULA)
  M-MEN
  D-DAYS
  W-WORK DONE
