Correct Answer: 150%
Solution : Let the third number be 100$x$. Then, the first number = 50% less than 100$x$ = 50$x$ The second number = 80% less than 100$x$ = 20$x$ So, the required percentage change = $\frac{\text{ first number – second number}}{\text{second number}} × 100$% = $\frac{50x-20x}{20x}$ × 100% = 150% Hence, the correct answer is 150%.
