By Harper

Step-by-step explanation:CP of 300 apples = Rs 50 per dozen

300 apples =

12

300

dozen

i.e 25 dozen

1 dozen = Rs 50

25 dozen = Rs (25×50)

= Rs 1250

∴ CP of 300 applies = Rs 1250

overall profit % should be 12%

∴ profit =

100

12×CP

=

100

12×1250

= Rs 150

∴ SP should be 1250 + 150 = Rs 1400

Now,

SP of 200 apples = Rs 50 per 10 apple

SP of 200 apples =

10

50

×200= Rs 1000

Now he has to make Rs 400 (1400 – 1000) by selling

last 100 apples

∴ SP of 100 apples = Rs 400

SP of 1 apple =

100

400

= Rs 4
