Explanation:

- Seller A and B sell wooden and plastic toys at the same unit prices.

- For seller A, the ratio of plastic to wooden toys sold is 3:8.

- Seller A sells wooden toys at a 2:3 ratio compared to seller B.

- Seller B’s total toy sales are 100 units.

- The number of plastic toys sold by seller B equals the number of wooden toys sold by seller A.

- The price of each wooden toy is twice that of a plastic toy.

To solve:

- Let x be the number of wooden toys sold by seller A.

- Then, seller B sells (3/2)x wooden toys, due to the 2:3 ratio.

- Seller B's total is 100 toys, which includes both wooden and plastic.

- The number of wooden toys A sold is equal to the number of plastic toys B sold; hence seller A sells (3/11) of the total 100 toys.

- This ratio makes x = 40, which represents both wooden toys by A and plastic toys by B.

The comparison:

- Wooden toys by A = 40.

- Plastic toys by B = 40.

The percentage increase or decrease comparison:

- The number of plastic toys sold by B is equal (0% more/less) than the wooden toys sold by A.

Thus, the correct answer is:

- "None of these" as the options do not provide 0%.
