Given :  Number 154N38  is divisible by 3 , 6 and 9

To Find : Value of digit N

Solution:

A number is Divisible by 3 if it is Divisible by 9

A number is Divisible by 6 if it is Divisible by 2 and 3

A number is Divisible by 9 is sum of digits is divisible by 9

A number is Divisible by 2 if unit digit is divisible by 2  means unit digit is

0 , 2 , 4 , 6 or 8
