The range is from -14 to 26, so look for the answer that contains this range. x>-100 contains the range, so A is correct.

But x>-100 means it’s greater than 26 as well which breaks the domain of inequality

I got Q10 as A, Q11 as D and need help in Q12.

It does not matter, We are not looking for exact range. We are looking at what MUST be true. For example: if a number is 2<x<4, it MUST be true that it is positive, that is x>0

SATYAM7777
Is the answer E for 12?
It would be B....we can divide both sides of inequality a^2x>a^2y by a postive value a^2 without changing the inequality sign, so a^2x/a^2 > a^2y/a^2 or x>y.

So why it’s not D, each sufficient, cause

ax>ay, a also can be cancelled leaving x>y

I have two more doubts for today. 19 and 21.
Do suggest me the answere.

Just a can’t be canceled because a can be negative also. However a^2 can be canceled because a^2 is always positive

I’m not a fan of cancelling out though. You can just do a(x-y) >0. Now if a is negative then (x-y) will be negative and if a is positive then (x-y) will be positive

I think you should go with the basics first, learn the basics of arithmetic, algebra, number systems , and then try to solve at least 20 questions a day, using this strategy I also ended up in my recent mock 715 overall.
