Question

Give two example of a number which is divisible by 3 but not 9 ,2but not 6,2 nd 4 but not 8

Answer 1

Therefore, 144 is divisible by both 2 and 3. [We know the rules of divisibility by 2, if the unit's place of the number is either 0 or multiple of 2]. 180 is divisible by 2. Since the unit place is 0, divisible by 2.[A number is divisible by 3, if the sum of its digits is a multiple of 3 or divisibility by 3].
