Question

In each of these questions two equations are given. You have to solve these equations and give answer.
I. $4x^2=25$
II. $2y^2-13y+21=0$

• A. If $x<y$
• B. If $x>y$
• C. If $x=y$
• D. If $x\ge y$
• E. If $x\le y$

Answer 1

The correct option is A If $x<y$

I. $4x^2=25$
or, $x^2=\frac{25}{4}$
or, $x=\pm \frac{5}{2}$
II. $2y^2-13y+21=0$
or, $2y^2-6y-7y+21=0$
or, $(y-3)(2y-7)=0$
or, $y=3,\frac{7}{2}$
Hence, y > x
