Hey Fellows,

Try this question.

Is a^2 + b^2 >= 130?

1. a/b = 3/11.

2. a < 3.

OA

.

I m confused between C n E. pls letme know where I m wrong.

clearly 2nd eq is not sufficient.

Take 1st eq... take a=3x and b =11x

put in the question.....we get

9x^2 + 121x^2 >= 130=>

130x^2 >=130 x^2>=1, thus we need to know whether this satisfy or not.

If we consider eq 2... a<3 that means x<1

Thus this should be C...but one case when x=1 we hav not consider this might take it to E.

Pls advice.

. So still E.

answer is YES.
