Data Sufficiency

A trader sold an article at $ 625. What is the profit percentage?

A) He gained $ 600 by selling 8 such articles.
B) The cost price of the article is $ 545 and transportation cost is $ 5 each


A) Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.

B)Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

C)BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.

D) EACH statement ALONE is sufficient.

E)Statements (1) and (2) TOGETHER are not sufficient.


I have chosen D . If I am wrong can anyone please explain where I am wrong ?

Thanks a lot .

Profit percentage is (profit/cost)*100
If we can find profit and cost of one article, then we can get the profit percentage after selling one article.

stmt-A=> we can get gain (or profit) of one article as 600/8
we already know selling price as 650. Now we can get cost price, which is (selling price - profit).
stmt-A alone is suff.

stmt-B=> If total cost consists of cost of the article and transportation charges only, then stmt-B alone is also sufficient to answer the Q. IMO, we can assume it so.

So your answer "D" must be true

But OA is C .
