x2 + (p+q)x + 150 = 0, m and n are two roots of equation(both are positive natural numbers) and m2+n2 = 325. Also the ratio of p and q is 2 : 3.
Then which of the equations are true:
(I) (m + n)2 = 6q
(II) pq = mn
(III) (m + n) = -(p + q)
1
Only equation I is true.
2
Only equation II and III are true.
3
Both equation I and II are true.
4
Both equation I and II are false.
5
Only equation I and III are true.
