This is just a 10 sec question 
Solution:
As we get a remainder 8 when divided by 10, we know all the units digit of multiples of 10 is 0. Thus the only possible units digit to get a remainder of 8 is 8.
And when we divide 8 by 5 we get a remainder of 3. This is same for all the number with units digit 8.
Answer:3
Hope this helps!

OA Explanation
Any number N when divided by a divisor \(x\) can be written as \(xQ + R\)
Where, Q = quotient and R = remainder
Here, \(N = 10Q + 8\)
when \(Q = 0\), \(N = 8\)
\(Q = 1\), \(N = 18\)
\(Q = 2\), \(N = 28\)
When we divide \(8, 18, 28, ... \) with \(5\), every time we are getting a remainder of \(3\)
