Question

If $x$ is $5$ percent of $r$ and $r$ is $20$ percent of $s$, what percent of $s$ is $x$ ?

• A. $1\%$
• B. $4\%$
• C. $10\%$
• D. $40\%$
• E. $100\%$

Answer 1

The correct option is A $1\%$

Given that $x$ is $5$ percent of $r$ and $r$ is $20$ percent of $s$.

It can be written as,

$x=\frac{5}{100}\times r$ and $r=\frac{20}{100}\times s$.

Now by substituting $r$ in $x$, we get

$x=\frac{20}{100}\times \frac{5}{100}\times s=\frac{1}{100}\times s$

Therefore, $x$ is $1$% of $s$
