Directions (next five questions) : In these questions, two equations numbered I and II are given. You have to solve both the equations and mark the appropriate answer.
I. 3x2-14x+15=0
II. 15y2-34y+15=0
3x2-9x-5x+15=0
3x(x-3)-5(x-3)=0
(3x-5)(x-3)=0
∴ x=5/3,3
15y2-25y-9y+15=0
5y(3y-5)-3(3y-5)=0
(5y-3)(3y-5)=0
∴ y = 3/5,5/3
Hence, x ≥ y
I. 3x2+13x+14=0
II. 8y2+26y+21=0
I. 3x2+11x+10=0
II. 2y2+13y+21=0
I. 4x2+17x+15=0
II. 3y2+19y+28=0
