  • Question

  • Options
  • A. ? 12000
  • B. ? 24000
  • C. ? 48000
  • D. Cannot be determined

  • Correct Answer
  • ? 24000 

    Explanation

    Let cost of one saree and shirt be x and y, respectively.
    2x + 4y = 16000 ....(i)
    x + 6y = 16000 ....(ii)

    On multiplying Eq. (ii) by 2 and subtracting from Eq. (i). we get
    2x + 4y = 16000
    2x + 12y = 32000
    -------------------------
    -8y = -16000
    ? y = 2000

    Putting the value of y in Eq. (ii), we get
    x +6 x 2000 = 16000
    ? x = 4000
    ? Cost of 12 shirts = 12y
    = 12 x 2000 = ? 24000
