A computer dealer initially offered a laptop for sale at a price that would have given him a 25% profit over his cost. What was his cost (in dollars)?

(1) The computer dealer eventually sold the laptop for $1150. (2) After the laptop was rated highly by a PC magazine, the computer dealer raised the price 15% and sold it for a profit of$350.

Solution:
Pre Analysis:
• Let the CP of the laptop be $$x$$
• According to the question stem, the marked price of the laptop is $$MP=x(1+\frac{25}{100})=1.25x$$
• We are asked the value of $$x$$

Statement 1: The computer dealer eventually sold the laptop for $1150 • Accoridng to this statement $$SP=1150$$ which doesn't help us in getting the value of x • If we knew that the laptop is sold at the MP with no further discount then we could have written 1150=1.25x • However, that information is not known • Thus, statement 1 alone is not sufficient and we can eliminate options A and D Statement 2: After the laptop was rated highly by a PC magazine, the computer dealer raised the price 15% and sold it for a profit of$350
• According to this question, $$SP=1.25x(1+\frac{15}{100})=1.25x\times 1.15$$
• And $$1.25x\times 1.15-x=350$$ which can be solved to get the value of x
• Thus, statement 2 alone is sufficient

Hence the right answer is Option B

Isnt the question badly worded? If B is supposed to be the answer I think it should say "After the laptop was rated highly by a PC magazine, the computer dealer raised the initial price by 15% and sold it for a profit of \$350". I answered "E" because in my mind the following could have happened:

1. Initial price set (25% profit)
2. Seller decides to discount by X% - maybe it was not selling fast enough
3. Review by the magazine comes out and he raises it again by 15%.

Happy to hear if my thinking is wrong.
