In a certain toy store, 20% of the international branded toys are the only premium category toys. If premium toys make up 10% of the total number of toys in the store, what percent of toys in the store are of international brands?

A. 10%

B. 20%

C. 40%

D. 50%

E. 60%

Let's assume the total international branded toys are 100.

Since 20% of these toys are premium category toys, the total number of premium

category toys is 20. Now, 20 is the total number of toys in the store, which is 10%

of the total number of the store. The total number of toys in the store is 200.

Therefore, the total percentage or toys that are of international brands are \(\frac{100}{200} = 50\)%

(Option D)
