Question

if the three digit number n27 i divisible by 9, then which of the following is a value of n.​

Answer 1

Answer:

Given 89y is divisible by 9

As we know that

If a number is divided by 9 then the sum of numbers must be divisible by 9

8+9+y must be also divided by 9

⟹17+y is divided by 9

So possibility is 17+y=18

⟹y=18−17=1

Answer 2

927 is divisible by 9

Given n27 is divisible by 9

As we know that

If a number is divided by 9 then the sum of numbers must be divisible by 9

n+2+7 must be also divided by 9

⟹n+9 is divided by 9

So possibility is 9+n=18

⟹ n= 9
