In each of the following questions, two equations are given. You have to solve them and give answer. (I) (x^2+14x+49=0) (II) (y^2+11y+30=0)

  1. If x>y

  2. If x≥y

  3. If x<y

  4. If x≤y

  5. If x=y or relationship can not be established

C Correct answer
Explanation

Equation (I) gives x = -7 (double root from (x+7)^2=0). Equation (II) gives y = -5 or y = -6 (from (y+5)(y+6)=0). Since -7 is less than both -5 and -6, x < y always holds.
