Question

If62x is divisible by 2 and x is a digit, what are the possible values of x​

Answer 1

If it is divisible by 2 means it will be an even number.

So the possible values of x are 1,2,3,4,5,6,7,8,9.

Answer 2

We know that the given number

67y19

is divisible by 9.

And, if a number is divisible by 9 then sum of digits must be a multiple of 9.

i.e., 6+7+y+1+9= multiple of 9

y+23=0,9,18,27…

Here y is a digit, where, y can have values between 0 and 9.

y+23=27 which gives y=4.

Hence, y=4.
