Step-by-step explanation:
Here :-
- Selling price of 10 mangoes is equal to the cost price of 12 mangoes
[tex]\begin{gathered}\end{gathered}[/tex]
Let the cost price of one mango be ₹1. So :-
- Cost Price of 10 mangoes = ₹10
- Selling Price of 10 mangoes = ₹12
↝ Here the selling price of 10 mangoes is equal to the cost price of 12 mangoes. It means selling price of 10 mangoes = cost price of 12 mangoes. So, the selling price of 12 mangoes is ₹12 and the cost price of 10 mangoes is ₹10.
[tex]\begin{gathered}\end{gathered}[/tex]
Fistly, finding the profit :-
[tex]{\dashrightarrow\sf{Profit = Selling \: Price - Cost \: Price}}[/tex]
[tex]{\dashrightarrow\sf{Profit = 12 - 10}}[/tex]
[tex]{\dashrightarrow{\sf{\underline{\red{Profit = Rs.2}}}}}[/tex]
∴ The profitis Rs.2.
[tex]\begin{gathered}\end{gathered}[/tex]
Now, finding the profit percentage :-
[tex]\dashrightarrow{{\sf{Profit \: \%= \dfrac{Profit }{Cost \: Price} \times 100}}}[/tex]
[tex]\dashrightarrow{{\sf{Profit \: \%= \dfrac{2 }{10} \times 100}}}[/tex]
[tex]\dashrightarrow{{\sf{Profit \: \%= \dfrac{2 \times 100 }{10}}}}[/tex]
[tex]\dashrightarrow{{\sf{Profit \: \%= \dfrac{200 }{10}}}}[/tex]
[tex]\dashrightarrow{{\sf{Profit \: \% = \cancel\dfrac{200 }{10}}}}[/tex]
[tex]{\dashrightarrow{\sf{\underline{\red{Profit \: \% = 20 \: \%}}}}}[/tex]
∴ The profit percent is 20%.
