  • Question
  • The product of two consecutive number odd number is 6723. What is the greater number?


  • Options
  • A. 89
  • B. 85
  • C. 91
  • D. 83

  • Correct Answer
  • 83 

    Explanation

    Let the two consecutive odd number be (x + 1) and (x + 3).
    According to question (x + 1) (x + 3) = 6723
    ? x2 + 3x + x + 3 = 6723
    ? x2 + 4x + 3 = 6723
    ? x2 + 4x - 6720 = 0
    ? x2 + 84x - 80x - 6720 = 0
    ? ( x - 80 )( x + 84 )= 0
    ? x = 80, (x ? -84)
    Hence, the greater number = 80 + 3 = 83
