If 17 is added to the product of two consecutive whole numbers, the result is always a/an
APrime number
BEven number
COdd number
DNone of these
Answer & Solution
Correct answer: C. Odd number
The product of two consecutive whole numbers is always even, because one of them must be even. Adding 17, which is odd, to an even number gives an odd number. It need not always be prime; for example, $16\times17+17=289$, which is composite.
