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!

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 --> eq-1 and What is a percent of c? ==> x = \frac{a}{100} * c = a*c*\frac{1}{100} --> eq-2 As, we know the value of a from the first equation eq-1 and after putting that value into eq-2, 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

If a,b and c are greater than 0 and a is twice as large as b percent of c then in terms of b and c , what is a percent of c ? A) 2bc/100 B) 2b (c^2) /1000 C) b (c^2) /5000 D)c (b^2) /5000 E) 5000b/(c^2) Could someone provide a solution to this problem ?

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
