Following is the Quantitative Aptitude quiz to help you practice with the best of latest pattern questions.

Directions (1-5): In each of these questions, two equation (I) and (II) are given. You have to solve both the equations and give answer 

Q1. I. 6x²+77x+121=0 
II. y²+9y-22=0

if x < y

if x > y

if x ≥ y

if x ≤ y

if x = y or no relationship can be established between x and y

Solution:

Q2. I. x = √625 
II. y = √676

if x < y
