Question : 34 of 40

Marks: +1, -0

The product of two successive numbers is 3192, what is the smaller number?

Solution:

Let the two successive numbers be x and (x + 1); then

x(x +1) = 3192

⇒ x^2 + x - 3192 = 0

⇒ (x + 57) (x -56) = 0

⇒ x = 56

(Taking positive value only)
Hence, smaller number = 56
