Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
There is no sign in (2) so i could not sell anything about it.
Regarding (1): It is obviously not enough. Assume that b is 0 and a is -1. Then the inequality is 0<-1 which is false Assume that b is -1 and a is -2. Then the inequality is -2<-1 which is true _________________
If my post is useful for you not be ashamed to KUDO me! Let kudo each other!
Yeah subhash, I misread (1) as saying that a is +ve, hence everything I wrote is for that case.. (why I always get a couple questions wrong in Q =/)
If we take ab>=0 as per the link, and a<0, then a is -ve, b is 0 or -ve.
choose a=-5. is -5 |b|<-5-b ??? For any neg integer b, RHS will at least be -4 while LHS will at most be -5. Therefore it would be (C).. only b can be 0! In that case it doesnt stand, 0 is not <a (as per statement 1), so the possibility of b=0 makes it (E).
