Answer:
Let us consider the numbers which are divisible by 4
4, 8, 12, 16, 20, 24, 28, 32, 36, 40….
Now let us consider the numbers which are divisible by 6
6, 12, 18, 24, 30 , 36, 42, 48, 54, 60,…….
So the number divisible by both 4 and 6 are
12, 24, …….
But we can observe that number 12, 36,… are divisible by both 4 and 6 but not divisible by 24.
So it is concluded that a number divisible by 4 and 6 is not divisible by 24.
