Direction: In each of these questions, two equations Ⅰ and Ⅱ are given. You have to solve both the equations and give answer
( 1 ) if x < y
( 2 ) if x > y
( 3 ) if x = y
( 4 ) if x ≥ y
( 5 ) if x ≤ y or no relationship can be established between x and y.

Correct Option: D
From the above given equations , we have
Ⅰ. 10x2 − 7x + 1 = 0
⇒ 10x2 − 5x − 2x + 1 = 0
⇒ 5x(2x − 1) − 1(2x − 1) = 0
⇒ (5x − 1)(2x − 1) = 0
∴ x = | , | ||
Ⅱ. 35y2 - 12y + 1 = 0
⇒ 35y2 − 7y + 5y + 1 = 0
⇒ 7y(5y − 1) − 1(5y − 1) = 0
⇒ (7y − 1)(5y − 1) = 0
∴ y = | , | ||
