      In a rectangular floor of length and breadth of 20

      metres and 9 metres, respectively, square tiles each of 3 metre edge length are to be laid. If the cost of each tile is Rs. 125, then find the total cost of the tiles to be laid in the room.
      A Rs. 2500 Correct Answer Incorrect Answer
      B Rs. 2400 Correct Answer Incorrect Answer
      C Rs. 2800 Correct Answer Incorrect Answer
      D Rs. 2000 Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Area of the rectangular room = 20 × 9 = 180 m2 Area of each tile = 3 × 3 = 9 m2 So, number of tiles to be laid in the room = (180/9) = 20 So, total cost of all the tiles laid in the room = 20 × 125 = Rs. 2500
