GIVEN: x = 10y + 5
Factor out 5 to get: x = 5(2y + 1)
We can see that x is a multiple of 5, which also means x is divisible by 5, which means the remainder will by ZERO when x is divided by 5
Answer: A

Given that x and y are positive integers and x = 10y + 5 and we need to find what is the remainder when x is divided by 5
x = 10y + 5 = 5*2y + 5 = 5*(2y + 1)
=> x when divided by 5 gives 2y + 1 as quotient and 0 as remainder
So, Answer will be A
Hope it helps!
