Find which of the following is even.

  1. 3 × 4    
  2. 5 × 7    
  3. 1 × 3    
  4. 9 × 5    

Hint:

a number N is said to be even if there exist a another number K , for which
N = 2 x K
second definition : when a even number is divided by 2 , we will not get any reminder

The correct answer is: 3 × 4


    3 x 4 is the correct answer
    Step 1: 5 × 7 = 35
    1 × 3 = 3
    9 × 5 = 45
    Step 2: Only 3 × 4 = 12 is even( because 12 is divisible by 2 and it not left reminder) The rest are odd
