完整解法

1. Calculate the number of defective toys in Carton A

Number of defective toys in A = $3\% \times 200 = \frac{3}{100} \times 200 = 6$

2. Calculate the number of defective toys in Carton B

Number of defective toys in B = $8\% \times 300 = \frac{8}{100} \times 300 = 24$

3. Calculate the total number of defective toys and total toys

Total defective toys = $6 + 24 = 30$
Total toys = $200 + 300 = 500$

4. Calculate the overall percentage of defective toys

Overall percentage = $\frac{30}{500} \times 100\% = \frac{3}{50} \times 100\% = 6\%$

答案

$6\%$ (option 3)
