Given details :

  • The profit gained js 45%

To find :

  • The cost price / Wholesale price

Solution :

We know that CP is ,

  • [tex]\sf\implies\:CP\:=\:\dfrac{100}{100\:+\:P\%}\:\times\:SP[/tex]

Put the values in the formula ,

  • [tex]\sf\implies\:CP\:=\:\dfrac{100}{100\:+\:45\%}\:\times\:899[/tex]

  • [tex]\sf\implies\:CP\:=\:\dfrac{100}{145}\:\times\:899[/tex]

  • Simplify 899 with 145 that gives us 6.2

  • [tex]\sf\implies\::\:CP\:=\:100\:\times\:6.2[/tex]

  • CP = $620
