questions is wrong

Answer 2

Amit bought 20 dozen copies for 10 rs per dozen

Cost price for Amit in total is = 20*10= Rs 200

Amit sold 10 dozen copies at 10% profit

Hence Amit sold each copy at Rs10 + 10% of 10= 10+1= Rs11 pe copy

For 10 dozen selling price is= ₹110

Now he sells the remaining 10 dozen for 20% Profit

therefore,
he sells one copy for ₹ 10+20%of 10
=₹12/Copy
For 10 dozen copy
10*12= ₹120

Total selling price is
₹120+₹110=₹230

Total cost price=₹200

Profit=230-200=₹30

Gain%= Profit/Cost price *100

Gain%= 30/200 *100 =15%
