Multiple choice general knowledge math & puzzles If x/y=4 and y is not '0' what % of x is 2x-y ? 150% 175% 125% 100% Reveal answer Fill a bubble to check yourself B Correct answer Explanation Given x/y = 4, we have x = 4y. Then 2x - y = 2(4y) - y = 7y. Since x = 4y, y = x/4. So 2x - y = 7(x/4) = 1.75x, which equals 175% of x.
