A clothing store has two pieces of clothes with different purchase prices, which are sold at 150 yuan. One of them makes 50% profit and the other loses 50%. In this transaction, how is the clothing store's profit?

I lost 100 yuan
A clothing (profit): set the cost as X, 150-x = 0.5x, x = 100 yuan
Profit = 150-100 = 50 yuan
B clothing (loss): set the cost as y, 150-y = - 0.5y, y = 300 yuan
Profit = 150-300 = - 150 yuan
Shop profit: 50 + (- 150) = - 100 yuan
So I lost 100 yuan
