  1. The product of two consecutive number odd number is 6723. What is the greater number ?
    1. 89
    2. 85
    3. 91
    4. 83
  1. Correct Option: D

    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
