Question: For $ a>b>c>0, $ the distance between (1, 1) and the point of intersection of the lines $ ax+by+c=0 $ and $ bx+ay+c=0 $ is less than $ 2\sqrt{2}. $ Then
Options:
A) $ a+b-c>0 $
B) $ a-b+c<0 $
C) $ a-b+c>0 $
D) $ a+b-c<0 $
Correct Answer: A $ \Rightarrow 2{{( 1+\frac{c}{a+b} )}^{2}}<8 $ $ \Rightarrow 1+\frac{c}{a+b}<2\Rightarrow a+b-c>0 $
