Answer 1

$\large{\boxed{\bold{Answer:}}}$


C.P of 12 lemons = 25rs


$cp \: of \: 1 \: lemon = \frac{25}{12} \\ \\ total \: lemons = \frac{5 \times 25}{12} \\ \\ = > \frac{125}{12} \\ \\ = > 10.416$

S. P of 5 lemons = 12rs


To find the gain,


$\frac{sp - cp}{cp \times 100} = \frac{12 - 10.416}{10.416 \times 100} \\ \\ gain = 15.2\%$

Here,

Selling price of Given 5 lemon=12

Using formula:-)

Gain %=Selling price-Cost price/Cost price×100

=12-125/12. /125/12×100

=12.10416/10.416×100
