(1) p is greater than 1/2.

(2) q is greater than 1/2.


Is \(p^2+q^2>1\)

Statement 1: \(p>\frac{1}{2}\)

so \(p^2>\frac{1}{4}\). but nothing mentioned about \(q\). Hence insufficient

Statement 2: \(q>\frac{1}{2}\)

so \(q^2>\frac{1}{4}\). but nothing mentioned about \(p\). Hence insufficient

combining 1 & 2 we get \(p^2+q^2>\frac{1}{4}+\frac{1}{4}\)

hence \(p^2+q^2>0.5\). So we can have both a Yes & No situation. Hence Insufficient

Option E
