A) 6 only B) 6 and 12 both C) 12 only D) by 18 only

Answer 1

Answer:

option B 6 and 12both

please do follow me i will follow u back if u follow me sure

Answer 2

Answer:

So the answer is below(Option a)

Step-by-step explanation:

Lets assume the value of n=1 as 1 is a natural number

Now put the value of n in the question and will get the value of the question as 18

18 is divisibe by 2,3,6,9,18 so if we check the divisbility rule of 2- last number should be even, for 3- sum of digits should be a multiple of 3, 6- the number should be divisible by 2 and 3 both, 9- again sum of digit

so the best option which satisfies the divisibility rule is A) as 6
