  • Question
  • An order was placed for the supply of a carpet whose breadth was 6 m and length was 1.44 times the breadth. What be the cost of a carpet whose length and breadth are 40% more and 25% more respectively than the first carpet. Given that the ratio of carpet is Rs. 45 per sq. m ?


  • Options
  • A. Rs. 4082.40
  • B. Rs. 1024.21
  • C. Rs. 2810.6
  • D. Rs. 3214

  • Correct Answer
  • Rs. 4082.40 

    Explanation

    Length of the first carpet = (1.44)(6) = 8.64 cm

    Area of the second carpet = 8.64(1 + 40/100) 6 (1 + 25/100)

    = 51.84(1.4)(5/4) sq m = (12.96)(7) sq m

    Cost of the second carpet = (45)(12.96 x 7) = 315 (13 - 0.04) = 4095 - 12.6 = Rs. 4082.40
