Hi

KanishkM,

I agree B is sufficient, but i think i'm missing something here,

Is the below inference wrong?

So we have

41-2ab

41=2ab

41/2=abso if we know a=5, why can't we find B?

If i want to find a value of something, how am i relating it to 0 ??

Highlighted will hold good, if question had mentioned that we can equate to 0. We can ideally manipulate the if part of the question.

a^2+b^2=41

from statement 1) a = 5, then

25 +b^2 = 41

b^2 = 16

b = +/- 4

Let me know if this helps

Is the OA correct ? is it B or D ??
