Directions (next six questions): In these questions, two equations numbered I and II are given. You have to solve both the equations and mark the appropriate option.
I. 2x2-9x+9=0
II y2-7y+12=0
2x2-6x-3x+9=0
2x(x-3)-3(x-3)=0
(x-3)(2x-3)=0
⇒ x=3,3/2
II. y2-7y+12=0
y2-4y-3y+12=0
y(y-4)-3(y-4)=0
(y-3)(y-4)=0
⇒ y=3,4ஃ x≤y
I 4x2-8x+3=0
II 4y2-15y+14=0
I 3x2-13x+14=
II 2y2-5y+3=0
I 2x2 – 21x +52 = 0
II 2y2 – 11y+12=0
Two mobile phones were purchased at the same price. One was sold at a profit of 30% and the second was sold at a price which was INR 2500/- less than the price at which the first was sold. If the overall profit earned by selling both the mobile phones was 5%, what was the cost price of one mobile phone
