Let's put this in a simple algebra format -
Divider + Remainder = Dividend
Per the question:
Divider = 4
Dividend = x
consider Remainder as y
y + 4 = x
y = x - 4
Statement 1:
y = 3 when x + 1 is divided by 4
3 = x + 1 - 4
x = 6
Therefore, we can find the value of y. Sufficient.
Statement 2:
y = 0 when 2x is divided by 4
0 = 2x + 4
0 = x + 2
x = -2
Based on the question, x is always positive. Therefore, insufficient.
Answer is (A).
