Problem
Q2: If the average of \( 5 x \) and \( 3 y \) is equal to \( 50 \% \) of \( 6 y \), what is the value of \( \frac{x}{y} \) ? a) \( \frac{1}{5} \) b) \( \frac{2}{3} \) c) \( \frac{3}{5} \) e) None of the above
Solution
Step 1 ：\( \frac{5x + 3y}{2} = \frac{1}{2} (6y) \)
Step 2 ：\( 5x + 3y = 6y \)
Step 3 ：\( \frac{x}{y} = \frac{3}{5} \)
