If n and p are two even numbers then which of them is not an even number :
Correct answer: D. (n * p) +1
- A. n + p
- B. n - p
- C. n+p / 2
- D. (n * p) +1
Explanation
All the options can be used for trial and error method, as n and p are two even numbers we can assume any two even numbers as the value of n and pAssuming n=4 and p=2A. n + p4+2 = 6 (an even number)B. n - p4-2= 2 (an even number)C. n+p / 2This is not applicable for all even numbers . for eg: if the two numbers are 12 and 16so the answer will be (12+16)/2=14so not correctD. (n * p) + 1(4*2) +1 = 9 ( not an even number)
