No cost price is given hence its not possible to calculate the actual answer.But don't worry I will simplify the equation till end that you can get the answer in fractions of sec
Solution:-
Let the Cost price be x
Mark up percent=40%
Now
Mark up=
![\\ \sf\longmapsto 40\%\:of\:x](https://img.qammunity.org/2022/formulas/mathematics/high-school/wfzkipmvslmms42isup4thyr5wcmusdroi.png)
![\\ \sf\longmapsto (40)/(100)* x](https://img.qammunity.org/2022/formulas/mathematics/high-school/j9uej80emir0vv6ojst828twxq77js2mzi.png)
![\\ \sf\longmapsto (40x)/(100)](https://img.qammunity.org/2022/formulas/mathematics/high-school/1maagj6cxx2z46l4fueom3kpz6yhlvl3c1.png)
![\\ \sf\longmapsto 0.04x](https://img.qammunity.org/2022/formulas/mathematics/high-school/yx7g8jz1zr4wzv7jb526ww1u5n7zsl4nln.png)
Just multiply The CP by 0.04 to get the answer
