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 0<a<1 then the first term 1/a is already more than one, so how can this work? 1/a + a/b = 1 since be cant be negative. (a>b>0)
thx.

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 a<b....but we are given a>b>0
9
So none of the value can fit in..

FLAWED question

Statement 1 is sufficient but statement 2 is flawed. kindly recheck the OA.
