if |r-6|=11 and |2q-12|=8, what could be the minimum possible value of q/r

both |r-6| = 11 & |2q-12| = 8 give two solutions, total 4 values of r & q.r-6= 11 & -r+6=11 => r=17,-52q-12=8 & -2q+12=8 => q= 10,-2These values give min as 10/-5 = -2

Can I get 90% plus if I start my preparation now? I mean the basics.

Yes of course u can !!! All u need is a little amount of dedication and sincere prep!!! 300 hours of prep + 12-15 mock tests should suffice !!!

your mocks paper are really good actually close to real exam but in real exam passage willbe asked from THE HINDU editorial but in craku you are asking some new topics which ain't from editorial.so plz provide HINDU EDITORIAL paragraphs as passage

No, there is not a rule that passages will be from Hindu editorial, but many mentors ask to read it becoz of its standard, this year, in CAT 2017,2 Passages came from The Guardian, one from aeon and one from livescience website. Hope you got it.
