Answer:
He sells the machine at Rs.14535.
Step-by-step Step-by-step explanation:
A person bought a copier machine for ₹15000 and spent ₹2100 on transporting it. So, the cost price will be :
![\begin{gathered} \quad\implies{\tt{C.P = Actual \: Price + Transposition }}\\\\ \quad\implies{\tt{C.P = 15000 + 2100 }}\\\\\qquad\implies{\tt{\underline{\underline{\purple{C.P = 17100}}}}} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/i1apnts1i7tp9ezhrdf6mr3nkobkroltxj.png)
Hence, the cost price of copier machine is Rs.17100.
Then he sold the machine for a loss of 15%. So, finding the selling price of copier machine :
![\begin{gathered}\qquad\implies{\tt{S.P = (100 - Loss\%)/(100) * C.P }}\\\\\qquad\implies{\tt{S.P = (100 - 15)/(100) * 17100 }}\\\\\qquad\implies{\tt{S.P = (85)/(100) * 17100 }}\\\\\qquad\implies{\tt{S.P = \frac{85}{1 \: \cancel{00}} * 171 \: \cancel{00}}}\\\\\qquad\implies{\tt{S.P =85 * 171 }}\\\\\qquad\implies{\tt{\underline{\underline{\pink{S.P =14535}}}}} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/clunctkuj1kndj1wwh8pv1vb9dzfdp4at4.png)
Hence, the selling price of copier machine is Rs.14535.
