Question

Find which one of the following is even.

  1. 3 × 9    
  2. 5 × 7    
  3. 5 × 3    
  4. 9 × 8    

hintHint:

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: 9 × 8


    9 x 8 is the correct answer
    Step 1: 3 × 9 = 27
    5 × 7 = 35
    5 × 3 = 15
    Step 2: Only 9 × 8 = 72 is even. because when we divide 72 by 2 we will not get any reminder, so 72 is a even number
