Answer 1

Step-by-step explanation:

profit =sp-cp

profit=910-840=70

profit%=p/cp×100

70/840×100=100/12

=8.34%

Answer 2

$\bf{\underline{\underline{Given :}}}$

$\mathsf{\bigstar\: Cost\:price\:(C.P) = Rs\: 840}$

$\mathsf{\bigstar\: Selling\:price\:(S.P) = Rs\: 910}$

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

$\mathsf{\bigstar\: Profit\: percentage}$

$\bf{\underline{\underline{Solution :}}}$

$\fbox{\mathtt{\red{Profit \: (P) = S.P - C.P}}}$

$\mathtt{\rightarrow\: Profit = Rs\: 910 - Rs\:840}$

$\mathtt{\rightarrow\: Profit = Rs\: 70}$

$\fbox{\mathtt{\green{Gain\:\% = {\frac{ Profit}{Cost\: Price}} × 100}}}$

$\mathtt{\rightarrow\: \Large{\frac{\cancel{70}}{\cancel{840}}} × \large{100} }$

$\mathtt{\rightarrow\:\Large{ \frac{100}{12}}}$

$\fbox{\Large{\mathtt{\rightarrow\: 8.33\: \%}}}$

∴ Gain percent = 8.33 %
