| Directions: In the following questions two equations numbered I and II are given. You have to solve both the equations and give answer. [RBI (Assistant) Scale 2011] |
| I. \[{{(x)}^{2}}=961\] |
| II. \[y=\sqrt{961}\] |
A) If \[x>y\]
B) If \[x\ge y\]
C) If \[x<y\]
D) If \[x\le y\]
E) If \[x=y\] or the relationship cannot be established
Correct Answer: E
Solution :
| I. \[{{x}^{2}}=961\] |
| \[\Rightarrow \]\[x=\pm \,\,\sqrt{961}\]\[\Rightarrow \]\[x=\pm \,\,31\] |
| II. \[y=\sqrt{961}\] |
| \[\Rightarrow \] \[y=\pm \,\,31\] |
| Hence, \[x=y.\] |
