Question

The cost price of 10 tables is equal to selling price of 8 tables. Find the loss or profit percent

Answer 1

$\underline{\textsf{Given:}}$

$\textsf{Cost price of 10 tablets = Selling price of 8 tablets}$

$\underline{\textsf{To find:}}$

$\textsf{Profit or loss percentage}$

$\underline{\textsf{Solution:}}$

$\textsf{Let the cost price of 1 tablet be Rs.x}$

$\textsf{As per given data,}$

$\textsf{C.P of 10 tablets = S.P of 8 tablets}$

$\implies\textsf{S.P of 8 tablets=10x}$

$\implies\textsf{S.P of 1 tablet}\mathsf{=\dfrac{10x}{8}}$

$\implies\textsf{S.P of 10 tablets}\mathsf{=\dfrac{100x}{8}}$

$\implies\textsf{S.P of 10 tablets}\mathsf{=Rs.12.5x}$

$\mathsf{Profit=S.P-C.P}$

$\mathsf{Profit=12.5x-10x}$

$\mathsf{Profit=Rs.\,2.5x}$

$\boxed{\mathsf{Profit\;percentage=\dfrac{Profit}{C.P}{\times}100}}$

$\mathsf{Profit\;percentage=\dfrac{2.5x}{10x}{\times}100}$

$\mathsf{Profit\;percentage=\dfrac{2.5}{10}{\times}100}$

$\mathsf{Profit\;percentage=2.5{\times}10}$

$\mathsf{Profit\;percentage=25\,\%}$

$\underline{\textsf{Answer:}}$

$\mathsf{Profit\;percentage\;is\;25\%}$
