64% of a number is 2592. What is 88% of that number?
(a)3202
(b)3458
(c)3564
(d)3826
(e)None of these
Answer
Answer (as printed): C
Explanation
Let the number be $x$. Then, $64 \%$ of $x=2592 \Rightarrow \frac{64 x}{100}=2592$ $\Rightarrow x=\left(\frac{2592 \times 100}{64}\right)=4050$. $\therefore 88 \%$ of $4050=\left(\frac{88}{100} \times 4050\right)=3564$.
