If we talk about profit, it is an extra-price, so the total is 140%.
2240 -- 140%
x -- 150%

\(x=2240*150/140=2400\)

1.4x = 2240
x=2240/1.4
so, 1.5X = 2240*1.5/1.4= 2400

I found the original buying price first because the math turned out to be easier.

2240 = X * 1.4 = X * (7/5). Therefore, X = 2240 * 5/7.

2240 is easily divided by 7 to be 320, which is then easily multiplied by 5 to give X = 1600. To get 50% profit, you need 1600 * 1.5 = 2400.

Answer: A
