      The diameter of the base of a cylindrical drum is 14 cm

      and its height is 15 cm. The drum is full of water and the water from the drum is transferred to β€˜n’ cuboidal tanks having dimension 14 cm Γ— 5 cm Γ— 11 cm, each. Find the value of β€˜n’.
      A 5 Correct Answer Incorrect Answer
      B 7 Correct Answer Incorrect Answer
      C 2 Correct Answer Incorrect Answer
      D 3 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Radius of the base of the cylindrical drum = 14/2 = 7 cm According to the question, Volume of cylindrical drum = volume of β€˜n’ cuboidal tanks Therefore, (22/7) Γ— 7 Γ— 7 Γ— 15 = n Γ— 14 Γ— 5 Γ— 11 Or, n = 2310/770 = 3
