In each question two equations numbered I and II are given. You have to solve both the equations and mark the appropriate answer. (I) 17x2+48x=9 (II) 13y2=32y-12

  1. If x > y

  2. If x ≥ y

  3. If x < y

  4. If x ≤ y

  5. If x = y or no relation can be established between x and y.

C Correct answer
Explanation

Equation I: 17x^2 + 48x - 9 = 0 gives x = -3 or x = 9/17. Equation II: 13y^2 - 32y + 12 = 0 gives y = 2 or y = 6/13. Comparing: -3 < 2 and -3 < 6/13; 9/17 < 2 but 9/17 > 6/13. For all valid comparisons, x < y.
