Answer:
Apples sold =15kg
S.P=Rs2100
C.P=Rs2100β12.5%ofRs2100
=Rs2100βRs262.5
=Rs1,837.5
C.P of 1 kg =Rs1225
Profit on 1 kg apple =15%ofRs122.5
S.P of 1 kg apple = Rs 122.5+15% of 122.5
=Rs122.5+18.375
=Rs140.875
Selling price for 15 kg apples = Rs. 2100
For 12% profit
C. P. =
100
100+ππππππ‘%
x S. P.
=

Cost price of 15 kg apples = Rs. 1875
For 20% profit
S. P. =
100+ππππππ‘ %
100
x C.P.
=
100+20

Selling price of 15 kg apples with
Selling price for 15 kg apples = Rs. 2100
For 12% profit
C. P. = 100/100+ππππππ‘%
x S. P. = 100/100+12x 2100 = 100/112x 2100
= Rs. 1875
Cost price of 15 kg apples = Rs. 1875
For 20% profit
S. P. = 100+ππππππ‘ %/100x C.P.= 100+20/100x 1875 =
120/100x 1875
= Rs. 2,250
Selling price of 15 kg apples with 20% profit= Rs. 2,250
S.P. for 15kg apples = Rs. 2,250
S.P. for 1 kg apples = 2250/15 = Rs. 150
Hence, selling price
