In the following question, one or two equation(s) is/are given. You have to solve both the equations and find the relation between ‘x’ and ‘y’ and mark correct answer.
I. x2– 10x + 21 = 0
II. y2– 16y + 63 = 0
In the following question, one or two equation(s) is/are given. You have to solve both the equations and find the relation between ‘x’ and ‘y’ and mark correct answer. I. x2– 10x + 21 = 0 II. y2– 16y + 63 = 0

x = y or the relation cannot be determinedExplanation
We will solve both the equations separately. Equation I: x 2 – 10x + 21 = 0 ⇒ x 2 – 7x – 3x + 21 = 0 ⇒ (x – 3) (x – 7) = 0 ⇒ x = 3 or x = 7 Equation II: y 2 – 16y + 63 = 0 ⇒ y 2 – 9y – 7y + 63 = 0 ⇒ (y – 7) (y – 9) = 0 ⇒ y = 7 y = 9 Comparing the values of x and y we get, x ≤ yRelated questions
