    Question

    The diameter of the base of a cylindrical drum is 70 cm

    and its height is 15 cm. The drum is full of water and the water from the drum is transferred to ‘n’ cuboidal tanks having dimension 10.5 cm × 5 cm × 11 cm, each. Find the value of ‘n’.
    A 110 Correct Answer Incorrect Answer
    B 120 Correct Answer Incorrect Answer
    C 100 Correct Answer Incorrect Answer
    D 130 Correct Answer Incorrect Answer

    Solution

    Radius of the base of the cylindrical drum = 70/2 = 35 cm According to the question, Volume of cylindrical drum = volume of ‘n’ cuboidal tanks Therefore, (22/7) × 35 × 35 × 15 = n × 10.5 × 5 × 11 Or, n = 57750/577.5 = 100
