increasing in order of size = a<b<c
now for QA: the numerator becomes 6a-5b
QB: the numerator becomes 6b-5c
If we take the 6* terms on the left and 5* terms on the right then it becomes
6*(a-b) 5*(b-c)
because, a, b, and c, are consecutive integers increasing in order, so a-b = b-c = -1
So the left side is -6 and the right side is -5
Hence, Ans B

In which cases can we do this (highlighted)?
