Question

In the question, a pair of equations is given. You have to find out the values of a and b and give answer :

I. 12a${}^2$ - 7a + 1 = 0

II. 15b${}^2$ - 16b + 4 = 0.

• A. if a < b
• B. if a ≤ b
• C. if a > b
• D. if a ≥ b

Answer 1

The correct option is A

if a < b

I. 12a${}^2$ - 7a + 1 = 0

Roots are 1/3,1/4.

II. 15b${}^2$ - 16b + 4 = 0

Roots are 2/3,2/5.

Therefore, answer should be a $<$b .
