Answer 2

Answer-

$\boxed{\boxed{\dfrac{y-x}{y}=0.2}}$

Solution-

As x is 20% less than y,

20% of y is,

$=y\times \dfrac{20}{100}$

So x is

$x=y-(y\times \dfrac{20}{100})$

$=y(1-\dfrac{20}{100})$

$=y(1-0.2)$

$=0.8y$

Then,

$\dfrac{y-x}{y}=\dfrac{y-0.8y}{y}=\dfrac{y(1-0.8)}{y}=1-0.8=0.2$

Therefore, the value of $\dfrac{y-x}{y}$ is 0.2
