I 2x 2 minus x minus 1 0 II 3y 2 minus 5y 2 0 ........

Quantitative Aptitude(IBPS CL) Arithmatic inequalities

Directions: Solve the following quadratic equation and mark the answer as per instructions.

I. 2x ² − x − 1 = 0

II. 3y ²− 5y + 2 = 0

x ≤ y

x < y

x = y or no relation can be established

x ≥ y

x>y

Correct answer(3)

I. 2x ² − 2x + x − 1 = 0

(2x + 1) (x – 1) = 0

x = - 1 2 , 1

II. 3y ² − 3y − 2y + 2 = 0

(3y – 2) (y – 1) = 0

y = 2 /3 , 1

clearly, no relation
