IBPS SO Prelims Exam Model Paper 1

x2 - 165 = 676
⇒ x2 = 676 + 165
⇒ x2 = 841
⇒x2 - (29)2 = 0
⇒ (x + 29) (x - 29) = 0
⇒ x = - 29 or x = 29
y2 - 120 = 841
⇒ y2 = 841 + 120
⇒ y2 - 961 = 0
⇒ y2 - (31)2 = 0
⇒ (y + 31) (y - 31) = 0
⇒ y = -31 or y = 31
When x = 29, x > y for y = -31 and x < y for y = 31
And when x = -29, x < y for y = 31 and x > y for y = -31
∴ The relationship cannot be established.
