Question

How many values of 'm' ('m' is a natural number) are possible if '6327m6' is divisible by 8?

Q: Answer-How many values of 'm' ('m' is a natural number) are possible if '6327m6' is divisible by 8?

A number is divisible by 8 when last three digits of number is divisible by 8. So, here we have to check whether 7m6 is divisible by 8 or not. Now, If m 3, then number becomes 736, which is divisible by 8 If m 7, then number becomes 776, which is divisible by 8 Thus, 7m6 is divisible by 8 when m 3 and 7. Hence, there are 2 possible values of m.
