Data Sufficiency (DS) | Re: Marvin bought video games at a standard price of $40 per video game.

Marvin bought video games at a standard price of $40 per video game. If he sold all video games that he bought at same price of $X each, what percentage profit did he make in this transaction?

(1) Instead of $X, if he had sold each video game at a price of $X/2, with the same cost price of $40, he would have incurred a loss of 37.5% in this transaction.

(2) Instead of $X, if he had sold each video game at a price of $(2*X), with the same cost price of $40, he would have gained 150% in this
