Solution:

We have cost price of apple = Rs.20 per kg
Cost price of 100kg apples = Rs.100 20
= Rs.2000
apples of 100kg = kgs
Selling price of 40kg = 93 percentage of CP of 40kg
= = Rs.744
Required selling price to get total profit 15 percentage = 115 percentage of total cost price
= = Rs.2300
selling price of remaining 60kg = Rs.2300 744= Rs.1556
Required profit 1556 1200 = Rs.356
Profit percentage =  = 29.66%
Hence option (A) is correct.
