if x and y are positive integers, what is the remainder when x is divided by y?
(1) When x is divided by 2y, the remainder is 4
(2) When x+y is divided by y, the remainder is 4
OA B
I'm not agree with OA, I would go for D, instead.
(1)Let's say remainder is R and result is Z, then x=2y*Z + R => x=y*(2Z) + R, so remainder for x/y would be R (Sufficient)
(2)Let's say remainder is R and result is Z, then x+y=y*Z + R => x=y*(Z-1) + R, so remainder for x/y would be R (Sufficient)
Can someone explain, if there is any problem in my explanation or suggest how OA could be correct?
