All the numbers that are divisible by 10 are also divisible by 5.
In this case the x=14,24,34,44,...
therefore these numbers when divided by 5 also leave the same remainder i.e. 4

Hi...
the equation formed is x=10y+4..
So when x is divided by 5, it means (10y+4) is divided by 5..
10y is divisible by 10 but 4 will leave a remainder of 4..
E
