Question

In the following questions, two equations numbered I and II are given. You have to solve both the equations and determine the relationship between them and give answer:

I. √(17x) + √51 = 0   

II. √(4y) + 3 = 0

A if x > y Correct Answer Incorrect Answer
B if y > x Correct Answer Incorrect Answer
C if y ≤ x Correct Answer Incorrect Answer
D if x ≤ y Correct Answer Incorrect Answer
E x = y or relationship cannot be determine Correct Answer Incorrect Answer

Solution

I. √(17x) = - √51 Squaring both sides, => 17x = 51 => x = 51/17 => x = 3 II. √(4y) = - 3 Squaring both sides, => 4y = 9 => 9/4 = 2.25 Hence, x > y
