1. The sum of three consecutive number is 123, The product of two smaller number is :

  • A. 900
  • B. 900
  • C. 900
  • D. 900

Answer: Option D

Explanation:

Let,
   the three numbers are x, x+1, x+2

   Here, two smaller numbers are x, x+1 respectively

   The sum of three consecutive number is     3X+3 = 123
                                                                                so, X= (123-3)/3
                                                                                    = 40
Two smallers numbers are 40 and 41 respectively
So their product is 40*41
 = 1640

Answere: 1640
