GMAT Data Sufficiency (DS) | Re: 2001, the closing price of stock A and stock B are the same.

Hi,

Stmt 1:

Let the closing stock price of both A and B (in 2001) be Rs100.

Case 1:

Let the closing stock price of B at the end of 2002 be Rs 200. Then, A is Rs 216.

Price increase of stock B = Rs 100

Case 2:

Let the closing stock price of B at the end of 2002 be Rs 300. Then, A is Rs 324.

Price increase of stock A = Rs 224
Price increase of stock
