Answer:
☥ [tex] \underline{ \underline{ \red{\large{\tt{S \: O \: L \: U \: T \: I \: O \: N}}}}} : [/tex]
☃ [tex] \large{ \tt{MP = x + 30\% \: of \: x}}[/tex]
➝ [tex] \large{ \tt{x + \frac{30}{100}x }}[/tex]
➝ [tex] \large{ \tt{x + 0.3x }}[/tex]
➝ [tex] \large{ \tt{1.3x}}[/tex]
☂ [tex] \large{ \tt{SP = 1.3x - 15\% \: of \: 1.3x}}[/tex]
⇾ [tex] \large{ \tt{1.3x - \frac{15}{100} \times 1.3x}}[/tex]
⇾ [tex] \large{ \tt{1.3x - 0.195x}}[/tex]
⇾ [tex] \large{ \tt{1.105x}}[/tex]
☼ [tex] \large{ \tt{Profit = SP - CP}}[/tex]
⟶ [tex] \large{ \tt{1.105x - x}}[/tex]
⟶ [tex] \large{ \tt{0.105x}}[/tex]
♨ [tex] \large{ \tt{P\% = \frac{Profit}{CP} \times 100 \%}}[/tex]
⤑ [tex] \large{ \tt{ \frac{0.105x}{x} \times 100\%}}[/tex]
⤑ [tex] \boxed{ \large{ \purple{\tt{10.5\%}}}}[/tex]
Hence , Profit % = 10.5 %
