    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 β€˜n’ cuboidal tanks having dimension 10.5 cm Γ— 5 cm Γ— 11 cm, each. Find the value of β€˜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 β€˜n’ cuboidal tanks Therefore, (22/7) Γ— 35 Γ— 35 Γ— 15 = n Γ— 10.5 Γ— 5 Γ— 11 Or, n = 57750/577.5 = 100
