Its amazing Avi . Instead of having to solve inequality for Statement 1 which i actually did you have just shown how beautifully statement 2 can be used as an advantage for St-1 . Really something to learn .
hi, Avi, I haven't gotten that it is impossible if one statement leads to a definitive yes and the other leads to a definitive no because someone lies. would you please clarify further?
Let's say our interpretation of statement (1) is that I'm in Africa, and our interpretation of statement (2) is that I'm in South America; do you agree that at least one of the statements must be lying? I can't be in both continents simultaneously! We know that on the GMAT the statements are always truthful, so our interpretation of the statements must have been incorrect.
Hello, Adding onto the previous question, I don’t understand how D is not the correct answer for the last question as it does lead to a definitive no on its own. And that is an answer. Why do the two answers have to be same?
I think what gave me pause here is that my understanding of how to approach DS is to consider statement 1 first , and then forget about it completely while you look at statement 2 to avoid bringing in your knowledge of statement 1 into statement 2 and picking C erroneously.
Makes sense. That's definitely a danger. This is a very advanced strategy, not to be used if you have a tendency to combine the statements prior to evaluating each on its own.
Yes. Here's an example: If p is a prime number, what is the value of p? (1) 2p = 38 (2) 13﹤p﹤23 Here, statement (1) is sufficient on its own, giving us p=19. We can use that as we go into statement (2) - we already know that statement (2) MUST allow for p=19, so all we have to do is find one OTHER prime number that statement (2) allows for (in this case, 17) in order to prove insufficiency.

amazing tip! not found anything close to this in my 200 days of prep. thanks a ton.
i was stuck in Q40s, cause i thought I was making silly mistakes, this one video turned my accuracy to 90% in DS..
I didn't get anything in the video, how he's rejecting the other option right away? It might be the case where both are sufficient in themselves
@@aditisingh-cn6dihe didnt reject it right away he used logic to disprove it

Hi Avi: if a DS is not a YES/NO question, can I apply this strategy?
Yes. Here's an example:
If p is a prime number, what is the value of p?
(1) 2p = 38
(2) 13﹤p﹤23
Here, statement (1) is sufficient on its own, giving us p=19. We can use that as we go into statement (2) - we already know that statement (2) MUST allow for p=19, so all we have to do is find one OTHER prime number that statement (2) allows for (in this case, 17) in order to prove insufficiency.
