Here, this formula is used when it is given in fractions.
So firstly we assume that R s .8000 is

because it will be the output value for the task.
Also, we assume that the

will be the value we have to find.
According to the question,

We know,

So we have two equations, and the left sides of both the equation have the same units, mathematically we can write the equation as,

So for solving the above equation, we multiply both of the sides by x, we get

So on solving it, we get

Now on dividing by 4 both the sides of the equation, we get

And on solving the above equation, we get
