Hi Bunuel,

Many thanks for this great question. I got the solution, the way you showed it. Only today, while I was attempting another question from the GMAT Club tests, I stumbled upon the sign method for solving inequalities. I was just wondering if you or someone else could kindly explain how to solve THIS question using the sign method. Many thanks!


Can you please tell me what "sign method" are you referring to? Thank you.

Bunuel,

Apologies if I got the name wrong. I just learnt about it today. Don't have strong handle on it.

I think VeritasPrepKarishma gave a detailed explanation on the process. Sorry, I am just learning it, so it's really rusty for me.
