If ab0

Question

If a>b>0 , is b<2?

1.  \frac{1}{a} >\frac{1}{2} 
2.  \frac{1}{a} + \frac{a}{b} = 1

goforgmat · Answer

From the given, a, b are both +ve , a!=b!= 0 1. 1/a >1/2 ==> a< 2 , hence b <2 . Sufficient. 2. let a=1 , 1+1/b >1 , hence a<1 and b < a < 1 .Sufficient. Hence D.

If a>b>0 , is b<2? 1. \frac{1}{a} >\frac{1}{2} \frac{2}{a>1}.....a<2 , And since a>b>0, b is also less than 2 Sufficient 2. \frac{1}{a} + \frac{a}{b} = 1 Three cases... a) a<1 ..... then 1/a >1 and so a/b should be less than 0 to negate excess in 1/a.. Means b<0.... But b>0, so not possible b) a=1....then 1/a=1/1=1 and so a/b that is 1/b , should be 0...Not possible c) a>1... Then 1/a<1 and a/b is also<1.... But a/b<1 means ab>0 9 So none of the value can fit in.. FLAWED question
