Question

In the following question, two equations numbered I and II are given. You have to solve both the equations and choose the appropriate answer.

I. 225x${}^2$ -- 4 = 0

II. $\sqrt{225y}+2=0$

• A. if x > y
• B. y > x
• C. x ≤ y
• D. x = y or the relationship cannot be established

Answer 1

The correct option is D

x = y or the relationship cannot be established

$\begin{array}{ccccccc}I.& 225x^2=4& \Rightarrow x^2=\frac{4}{225}\Rightarrow x=\pm \frac{2}{15}II.& \sqrt{225y}+2=0& \Rightarrow \sqrt{225y}=-2Squaringonbothsides,& 225y=4& \Rightarrow y=\frac{4}{225}\end{array}$
