A mam buy 9 apples for rs 9.60.he sells at 11for rs 12.find the gain and lost percentage

Answer 1

Hiii....
Here is your answer...

Solution:-
A man buy 9 apple for ₹9.60
Cost price of 1 apple=
$= > \frac{9.6}{9} = \frac{96}{90} = \frac{16}{15}$
Selling price of 11 apple=₹12
Selling price of 1 apple=
$= > \frac{12}{11}$
Since,
$\frac{16}{15} < \frac{12}{11}$
CP<SP

So,Gain=Sp-Cp
$= > \frac{12}{11} - \frac{16}{15} \\ = > \frac{4}{165}$
$gain\% = \frac{gain}{cp} \times 100$
$= > \frac{ \frac{4}{165} }{ \frac{16}{15} } \times 100$
$= > \frac{4}{165} \times \frac{15}{16} \times 100 \\ = > \frac{25}{11} \\ = > 2.27$
Hence,he gained 2.27℅
