Answer 2

Answer:  The required value of c is 0.25.

Step-by-step explanation:  Given that 8 is 4% of a, 4 is 8% of b and $c=\dfrac{b}{a}.$

We are to find the value of c.

According to the given information, we have

$8=4\%\times a\\\\\\\Rightarrow 8=\dfrac{4}{100}\times a\\\\\\\Rightarrow a=\dfrac{800}{4}\\\\\Rightarrow a=200$

and

$4=8\%\times b\\\\\\\Rightarrow 4=\dfrac{8}{100}\times b\\\\\\\Rightarrow b=\dfrac{400}{8}\\\\\Rightarrow b=50.$

Therefore, the value of c is given by

$c=\dfrac{b}{a}=\dfrac{50}{200}=\dfrac{1}{4}=0.25.$

Thus, the required value of c is 0.25.
