Hi kirub,
Unfortunately there is no easy explanation for this. As I pointed out in the thread above, these inconsistencies do happen. It's important to note that the timeframe you took the test in is important (we don't know when the other person took the test), and also people often just mis-remember their breakdown. Perhaps he got a Quant 48, not 49.
I understand it's frustrating but it's an unfortunate part of the process.
Best of luck with your applications!
