What number (n) must be inserted into the number 3n, 85n for it to be divisible by 6?

N = number that must be inserted in the given numbers to be divisible by 6

=> 3n

=> 85n

Now, let’s find a best number that will multiplied with both given number and is divisible with 6.

=> 85n / 6

=> 85 (6) / 6

=> 510 / 6

=>n = 6

now, let’s try to 3

=> 3 (6) / 6

=> 18 / 6

=> 3

Thus, the value of N is 6 because it is divisible by 6 when multiplied to the given number.
