What is the value of the two-digit positive integer n?
(1) When n is divided by 5, the remainder is equal to the tens digit of n.

Any help on this one would be much appreciated! Thanks

Take the LCM of 9 and 5 which is 45. Since remainder is tens digit, add 4 to 45 = 49
Now, 49/5 = 9 + remainder ->4
49/9 = 5 + remainder ->4
Thanks a lot
