Answer:
1)C.P. of 1 apple =Rs.
9
9.60
=Rs.1.06
S.P. of 11 apples=Rs.12
∴ S.P. of 1 apple=Rs.
11
12
=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
=
11.66
0.34
×100
Gain%=2.91%.
W
2)= 225 + 15 = 240 Rs. Gain = 300 – 240 = 60 Rs. Hence option [C] is the right answer.

Answer:
1)
C.P. of 1 apple =Rs. 99.60
=Rs.1.06
S.P. of 11 apples=Rs.12
∴ S.P. of 1 apple=Rs. 1112
=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
= 11.660.34×100
Gain%=2.91%
2)
Cost price of radio= Bought price+overhead expanses
Hence, CP=Rs. (225+15)=Rs. 240
SP=Rs. 300.
Since, SP>CP, so retailer get profit.
Profit=SP−CP=300−240=Rs. 60
Profit(%)= CP
profit ×100
= 24060×100=25%
