give step by step explanation
or else...​

Answer 1

Answer:

Gain%=2.91%

Step-by-step explanation:

C.P. of 1 apple =Rs. 9.60/9

=Rs.1.06

S.P. of 11 apples=Rs.12

∴ S.P. of 1 apple=Rs.12/11

=Rs.1.09

∴ C.P. of 11 apples=Rs.1.06×11

C.P.=Rs.11.66

S.P. of 11 apples=Rs.12

∴gain=S.P.−C.P.

Gain =12−11.66

Gain =0.34

Gain%= C.P/Gain ×100

=0.34/11.66x 100

Gain%=2.91%.

Answer 2

$\huge\tt\colorbox{lime}{Answer ✌️}$

C.P. of 1 apple =Rs.$\frac{9.60}{9}$=Rs.1.06

S.P. of 11 apples=Rs.12

∴ S.P. of 1 apple=Rs.$\frac{12}{11}$

=Rs.1.09

∴ C.P. of 11 apples=Rs.1.06×11

C.P.=Rs.11.66

S.P. of 11 apples=Rs.12

∴gain=S.P.−C.P.

Gain =12−11.66

Gain =0.34

Gain%=$\frac{gain}{CP}$×100

=$\frac{0.34}{11.66}$×100

=Gain%=2.91%.
