Step-by-step explanation:
Here :-
- Selling price of 25 balls is equal to the Cost of 15 balls
[tex]\begin{gathered}\end{gathered}[/tex]
Let the cost price of one ball is ₹1. So ;-
- Cost price of 25 balls = ₹25
- Cost price of 15 balls = ₹15
↝ Here the selling price of 25 balls is equal to the cost of 15 balls. It means C.P of 15 balls = S.P of 25 balls. So, the selling price of 25 balls is ₹15.
[tex]\begin{gathered}\end{gathered}[/tex]
Firstly, finding the loss :-
[tex]{\dashrightarrow{\sf{Loss = Cost \: Price - Selling \: Price}}}[/tex]
[tex]{\dashrightarrow{\sf{Loss = 25 - 15}}}[/tex]
[tex]{\dashrightarrow{\sf{\underline{\red{Loss =Rs.10}}}}}[/tex]
∴ The loss is Rs.10.
[tex]\begin{gathered}\end{gathered}[/tex]
Now, finding the loss percentage :-
[tex]{\dashrightarrow{\sf{Loss\: \%= \dfrac{Loss }{Cost \: Price} \times 100}}}[/tex]
[tex]{\dashrightarrow{\sf{Loss\: \%= \dfrac{10 }{25} \times 100}}}[/tex]
[tex]{\dashrightarrow{\sf{Loss\: \%= \dfrac{10 \times 100 }{25}}}}[/tex]
[tex]{\dashrightarrow{\sf{Loss\: \%= \dfrac{1000 }{25}}}}[/tex]
[tex]{\dashrightarrow{\sf{Loss\: \%=\cancel{\dfrac{1000 }{25}}}}}[/tex]
[tex]{\dashrightarrow{\sf{\underline{\red{Loss\: \%=40 \: \%}}}}}[/tex]
∴ The loss percent is 40%.
