  • Question
  • 4/7 of a pole is in the mud. When 1/3 of it is pulled out, 250 cm of the pole is still in the mud. Find the full length of the pole .


  • Options
  • A. 1000
  • B. 1100
  • C. 950
  • D. 1050

  • Correct Answer
  • 1050 

    Explanation

    Let us assume length of pole is L.
    Length of the pole in Mud is = L x 4/7 = 4L/7
    Length of the Pole which is pulled out = L x 1/3 = L/3
    Length of the pole is still in mud = Length of the pole in Mud - Length of the Pole which is pulled out
    Length of the pole is still in mud = 4L/7 - L/3
    According to question,
    Length of the pole is still in mud = 250
    4L/7 - L/3 = 250
    (4L x 3 - L x 7)/7 x 3 = 250
    12L - 7L = 250 x 21
    5L = 250 x 21
    L = 250 x 21/5
    L = 50 x 21
    L = 1050
