I am not 100% sure but here is what I think
6=20/100*200/100*x
6*5/2=x
30/2=x
x=15

Should the answer be 10? 200% of 10 is 30 and 20% of 30 is 6

Posted from my mobile device

Recall that 20% is 0.2 and that 200% is 2.

6 = (0.2)(2)(x)

6 = 0.4(x)

6/0.4 = x

60/4 = x

15 = x

Let number be x.
20% of 200% of x = 6
\(\frac{20}{100}\) * \(\frac{200}{100}\) * x = 6

x = \(\frac{6 * 100 * 100}{20 * 200}\) = 15
Answer A...
