Hello,

I have issues understanding the PS#218 and DS#72 from OG15.

Can someone provide a better explanation than OG??

Thanks

For sorting/searching purposes, it'll be easier for other users if you make separate threads for these two questions and post the second question in the Data Sufficiency section.

Also be sure to post the text of the problem itself, that saves a lot of time and helps other students who don't have that edition of the OG.
