1. x+y=30
2.\(y^2\) >10



1. x+y=30....... no specific info for xor y .... Thus NS.
when y=31, x=-1
when y=30, x=0
when y=29, x=1

2.\(y^2\) >10....... no specific info for x.... Thus NS.

1+2 ====>
when \(y^2\)=900, y=+30,-30 & x=0,60..... no specific answer................. Thus NS

Hence would go for Option E.

Statement 1: x + y = 30
if y is small x must be +ve such as x = 32, y = -2 but if y is large x must be -ve such as -5(x) + 35(y). Hence, Insufficient
Statement 2: y^2 >10
No mention of x. Hence, insufficient
Combining both:
Consider just 2 extreme values for y. Let's say 4 and 100. In first case x will be +ve but in second case, it'll be -ve. Hence, Insufficient.
