seems laxi is in vacation. so i want to try and go with B.

from i, x and y could be anything so, we donot know what is left when x is divided by y.

from ii, if 4 is reminder when x+y is divided by y, then it is also 4 when x is divided by y.

i assume that x and y are not integers.

Statement 1:
x = 2my + 4, where m is an integer, so 2 m is an integer too.
=>x could be changing based on the value of y.

Statement 2:
x + y = ny + 4, where n is an integer.
=> x = (n-1)y + 4. (If n an integer, n-1 is an integer too).
=> x could be changing based on the value of y.

Statement 1 & 2:
Both statements are of the same form. So useless.

Ans: E

Actually I get B.

(x+y)/y = x/y +1

plugging numbers u see that x/y also leave a remainder of 1!

For (1), we know that x=2yn+4 for some integer n

If y is greater than 4, x is some multiple of y +4, so the remainder is 4
If y is not greater than 4, the remainder with be less than 4

So (1) is not suff.

As for (2) x/y +1= n +4/y for some integer n

So x/y= (n-1) +4/y
i.e. x= (n-1)y +4 Therefore, x is some multiple of y + 4
We know y is greater than 4 (divisor is always greater than remainder).
Therefore, remainder is 4 (2) is suff

Answer: B
