Hi Hemanth,

It would be great if you could post each question separately.

It would be easier for everyone to respond and relate.

Thanks
Komal

1st

The reason why A is also SUFF:

xz is even that means either x or z or both are even. If x is even, then y and z are even. If x is odd then z has to be even. So either way z is even.


2nd

The reason why B is INSUFF:

r > 100( sqrt 1.15 - 1 )
r > 7.2% doesn't answer the question is r > 8%


3rd
