Question

Q68.

I. 6x² – 7x + 2 = 0

II. 10y² – 11y + 3 = 0

1. A. If x=y or no relation can be established (Correct answer)
2. B. If xy
3. C. If x<y
4. D. If x≥y
5. E. If x≤y

Correct Answer

Option A — If x=y or no relation can be established

Detailed Solution & Explanation

The correct answer is If x=y or no relation can be established.

Key Points

• I: x = (7±1)/12 → x = 2/3 or 1/2. II: y = (11±1)/20 → y = 3/5 or 1/2. Comparing: x=1/2,y=1/2 → equal; x=2/3,y=3/5 → x>y; x=1/2,y=3/5 → x<y. Mixed relations → no definite relation.
