Let the price of the stock A be A and the price of the stock B be B.
We are told that the price of stock A increases by 25%, making cost 1.25A
Similarly, the price of stock B is decreased by 25%, making cost 0.75B

1. \(1.25A = 0.75B\) -> \(\frac{A}{B} = \frac{3}{5}\) -> \(A = \frac{3B}{5}\)
Therefore, the original price of stock A was 60% that of stock B (Sufficient)

2. \(0.25A = \frac{3}{20}*B\) -> \(\frac{A}{4} = \frac{3B}{20}\) -> \(A = \frac{3B}{5}\)
Therefore, the original price of stock A was 60% that of stock B (Sufficient - Option D)
