In the following question- two equations numbered I and II are given- Solve both the equations and mark the appropriate option-I- -784 x -1234-1486II- -1089 y -2081-2345A- if x-yB- if x - yC- if x-y or no relation can be established between x and yD- if x - yE- if x-y

The correct option is A if x gt; yI. √(784)x = 1486 1234 = 252 ⇒ x = 252/√(784) = 252/28 = 9 II. √(1089)y = 2345 2081 = 264 ⇒ y = 264/√(1089) = 264/33 ...

Solution

The correct option is B if x > y
$I . \sqrt{784} x = 1486 - 1234 = 252 \Rightarrow x = \frac{252}{\sqrt{784}} = \frac{252}{28} = 9$

$I I . \sqrt{1089} y = 2345 - 2081 = 264 \Rightarrow y = \frac{264}{\sqrt{1089}} = \frac{264}{33} = 8$

In the following question, two equations numbered I and II are given. Solve both the equations and mark the appropriate option: I. √784x+1234 = 1486 II. √1089y+2081 = 2345

The correct option is B if x > yI. √784x=1486−1234=252⇒x=252√784=25228=9 II. √1089y=2345−2081=264⇒y=264√1089=26433=8

In the following question, two equations numbered I and II are given. Solve both the equations and mark the appropriate option:

$I . \sqrt{784} x + 1234 = 1486$
$I I . \sqrt{1089} y + 2081 = 2345$

The correct option is B if x > y
$I . \sqrt{784} x = 1486 - 1234 = 252 \Rightarrow x = \frac{252}{\sqrt{784}} = \frac{252}{28} = 9$

$I I . \sqrt{1089} y = 2345 - 2081 = 264 \Rightarrow y = \frac{264}{\sqrt{1089}} = \frac{264}{33} = 8$
