Answer: CExplanation:We can use Word Translation to translate the wording into mathematics and Algebra to solve step by step; \(a\) is twice \(b\) percent of \(c\) ==> \(a = 2 * \frac{b}{100} * c = 2bc/100\) > eq1 and What is \(a\) percent of \(c\)? ==> \(x = \frac{a}{100} * c = a*c*\frac{1}{100}\) > eq2 As, we know the value of \(a\) from the first equation eq1 and after putting that value into eq2, we get; \(x = \frac{2bc}{100}*c*\frac{1}{100} = \frac{bc}{50} *c*\frac{1}{100}= \frac{bc^2}{50} * \frac{1}{100} = \frac{bc^2}{5000}\). Which is option C

Thanks Bunuel.. I misunderstood the question's last part as What percent is a of c.... and hence I was getting 2b as the answer!

As per me the best way to solve this question is to Pick Smart Numbers & then verify the options

Let this be equation 1We need a%c in terms of b. So Multiply equation 1 with c/100 we get ac/100=2bc^2/10000 Therefore Ans is C

b percent of c : \(\frac{bc}{100}\) a is twice as large as b percent of c: a = \(\frac{2bc}{100}=\frac{bc}{50}\) What is a percent of c? a percent of c: \(\frac{ac}{100} = \frac{bc}{50}*\frac{c}{100}=\frac{bc^2}{5000}\) Answer: C

lets say a = 10 and b=5 so as per given info. 10 = 2*5*c/100 Which will give c = 100 substitute the value of 'b' and 'c' in in answer choices to get value 'a'.
