The product of two consecutive odd numbers is 6723. Find is the greater number.

Answer»

83



Let the first odd NUMBER be X.
Then, the other odd number would be x + 2.
∴ x(x+2) = 6723
= x2 + 2x = 6723
= x2 + 2x = 6723
= x2 + 2x - 6723 = 0
= x2 + 83 - 81 x - 6723 = 0
= x(x+83) - 81 (x + 83) = 0
= (x + 83) (x - 81) = 0
= (x + 83) (x - 81) = 0
= x - 81 = 0
∴ x = 81
Hence, GREATER number = x + 2 = 81 + 2 = 83
