100% of 100 when added to 200% of 200 would result 

Correct option is C

Let's break this down step by step:

• 100% of 100 = $$\frac{100}{100} \times 100 = 100$$​​
• 200% of 200 = $$\frac{200}{100} \times 200 = 400$$​​

Now, adding these values together:

100 + 400 = 500

So, the correct answer is (C) 500
