Tricky percentage OG DS

The price per share of Stock X increased by 10 percent over the same time period that the price per share of Stock Y decreased by 10 percent. The reduced price per share of Stock Y was what percent of the original price per share of Stock X?

1) The increased price per share of Stock X was equal to the original price per share of Stock Y.

2) The increase in the price per share of Stock X was 10/11th the decrease in the price per share of Stock Y.

Dear Striver

You could probably figure this out from my previous post to you, but here's the video solution.

Again, for anyone else reading --- I have posted a video solution for every single Quant question in both the OG12 and the OG13.

Please let me know if anyone reading this has any further questions.

Mike :)
