Solution

The correct option is A 10, 12, 14
Let the smallest even number be '2x'.
Because, the difference between any two consecutive even numbers is 2.
So, the other two numbers are 2x+2 and 2x+4.
2x+(2x+2)+(2x+4)=36 6x+6=36 6x=366 6x=30 x=306 x=5

2x=2×5=10
2x+2=2×5+2=12
2x+4=2×5+4=14
Thus, the three consecutive even numbers are 10, 12, 14.
