B. 20%

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)

0.2 * International=0.1 *total
So,international = 50% of total toys.

0.20 × i (international) = p (premium)

0.2 i = 0.10 × T(Total )

i = 0.50 T

A simple way to understand this problem is as follows:
(We need to find the value of C)
Assume that total number of toys are 100.
We know, 10% of the toys are Premium (10 toys) and only International Brands offer premium toys.
So,
$$A=10$$
$$D=0$$
$$G=10$$

Because 20% of the International Brands offer Premium toys, total number of premium toys is equal to -
$$x*\frac{20}{100} = 10$$
$$x=50$$

So
$$C=50$$
$$B=40$$

$$C=50$$
Therefore, 50% of the toys are of an International Brand.

Option D is correct

B. 20%
C. 40%
D. 50%
E. 60%

Assume 100 toys. 10 percent are premium:

All 10 premium toys are international

20% of all international toys, I, are premium

So 10 toys represent 20% of all international toys

$$10 = .20I$$
$$I=\frac{10}{0.2}=\frac{100}{2}=50$$

International toys: 50
Total toys: 100

International toys are 50% of all toys.

Solution

Given:
• In a certain toy store, 20% of the international branded toys are the only premium category toys.
• Premium toys make up 10% of the total number of toys in the store

To find:
• What percent of toys in the store are of international brands

Approach and Working:
If we assume that there are total 100 toys in the store, then we can say,
• Premium toys = 10% of 100 = 10

Now, these 10 toys are 20% of the international branded toys.
So, if we assume international branded toys are T in number, then we can say
• 20% of T = 10
Or, $$\frac{T}{5}$$ = 10
Or, T = 50

Therefore, international branded toys as a percentage of total toys = $$\frac{50}{100} * 100$$ = 50%

Hence, the correct answer is option D.

Let International Brands be "IT" and Total be "T"

so, IT * 20/100 = 10/100 * T,

therefore IT = 50/100 * T, so 50%
