One-eighth of a number is 41.5. What will 69% of that number be ?

Answer: Option C

Let the number be x
Then,
$$\begin{array}{rl}& \Rightarrow \frac{1}{8}x=41.5\\ & \Rightarrow x=41.5\times 8\\ & \Rightarrow x=332\\ & \therefore 69\%\text{of}332\\ & =\left(\frac{69}{100}\times 332\right)\\ & =229.08\end{array}$$
