  • Question
  • A class is 6 meters 24 centimeters in length and 4 meters 32 centimeters in width. Find the least number of square tiles of equal size required to cover the entire floor of the class room ?


  • Options
  • A. 115
  • B. 117
  • C. 116
  • D. 114

  • Correct Answer
  • 117 

    Explanation

    Length = 6 m 24 cm = 624 cm
    Width = 4 m 32 cm = 432 cm
    HCF of 624 and 432 = 48
    Number of square tiles required = (624 x 432)/(48 x 48) = 13 x 9 = 117.
