Answer 1

Profit = Selling Price - Cost Price

\begin{gathered} Profit + Cost\: Price = Selling \:Price \\\implies < br / > < br / > \frac{x}{6} + x = 1505 \\\implies \frac{x+6x}{6} = 1505 \\\implies 7x = 1505 \times 6 \\\implies x= \frac{1505\times 6}{7}\\\implies x = 1290\end{gathered}Profit+CostPrice=SellingPrice⟹<br/><br/>6x+x=1505⟹6x+6x=1505⟹7x=1505×6⟹x=71505×6⟹x=1290
