ANSWER WITH STEPS !!!!!

THIS Q IS OF 20 POINTS. SPAMS WILL BE REPORTED.

Answer 1

cost price of 9 apples = 9.60 rs

so , cost price of 1 apple = 9.60 /9

selling price of 11 apples = 12 rs

so selling price of 1 apple = 12 / 11 rs

so , gain = 12/11 - 9.6/9

= 108 - 105.6 / 99

= 2.4 /99

so

cost 9.60 / 9 rs ----- profit 2.4/99 rs

cost 100 rs ------ profit ???


profit percentage × 9.6 / 9 = (2.4 / 99) × 100

profit percentage × 9.6 / 9 = 240 / 99

profit percentage = 240 ×9 / 99 × 9.6

profit percentage = 2.27 %

Answer 2

Hiii...
Here is your answer...

Solution:-
CP of 9 apple=₹9.60
So,CP of 1 apple=
$= > \frac{9.60}{9} = \frac{960}{900} = \frac{16}{15}$
SP of 11 apple is =₹12
So,Sp of 1 apple=
$= > \frac{12}{11}$
Since,
$\frac{16}{15 } < \frac{12}{11}$
CP<SP
Therefore,
Gain=SP-CP
$= > \frac{12}{11} - \frac{16}{15} \\ = > \frac{180 - 176}{165}$
$= > \frac{4}{165}$
Now,
Gain℅=
$= > \frac{gain}{cp} \times 100 \\ = > \frac{ \frac{4}{165} }{ \frac{16}{15} } \times 100$
$= > \frac{4}{165} \times \frac{15}{16} \times 100 \\ = > \frac{75}{33}$
$= > 2.27$
Hence,he gain 2.27℅
