Answer 1

$$\begin{gathered} Dearstudent, \\ LettheCPofthetoycar=Rsx \\ SPofthetoycar=Rs560 \\ Now,itisgiventhatthereisaprofitof20\%onsellingthistoycar. \\ profit\%=\left[\frac{profit}{CP}\times 100\right]\% \\ \Rightarrow 20=\frac{(SP-CP)}{x}\times 100 \\ \Rightarrow 20=\frac{(560-x)}{x}\times 100 \\ \Rightarrow 20x=56000-100x \\ \Rightarrow 20x+100x=56000 \\ \Rightarrow 120x=56000 \\ \Rightarrow x=\frac{56000}{120} \\ \Rightarrow x=466.67 \\ Hence,\cos tpriceofthetoycarisRs466.67 \\ Regards \end{gathered}$$
