The cost of toolset before the discount was applied is:
Rs. 521.5189
It is given that:
A tool set has been discounted down to a price of Rs 412.00.
The percent discount that is provided to us is: 21%
Let the actual price of toolset be: Rs. x
This means that:
[tex]x-21\%\ of x=412\\\\i.e.\\\\x-0.21x=412\\\\i.e.\\\\(1-0.21)x=412\\\\i.e.\\\\0.79x=412\\\\i.e.\\\\x=\dfrac{412}{0.79}\\\\x=521.5189[/tex]
Hence, the actual price of toolset i.e. cost before discount is:
