x% of x is the same as 10% of
Answer & Solution
Correct Answer:
Option
B
Let x% of x = 10% of y
Then,
$$\eqalign{ & \Rightarrow \frac{x}{{100}} \times x = \frac{{10}}{{100}} \times y \cr & \Rightarrow y = \frac{{{x^2}}}{{100}} \times 10 \cr & \Rightarrow y = \frac{{{x^2}}}{{10}} \cr} $$
Then,
$$\eqalign{ & \Rightarrow \frac{x}{{100}} \times x = \frac{{10}}{{100}} \times y \cr & \Rightarrow y = \frac{{{x^2}}}{{100}} \times 10 \cr & \Rightarrow y = \frac{{{x^2}}}{{10}} \cr} $$
