In the following question two equations are given in variables X and Y. You have to solve these equations and determine the relation between X and Y.
A) `x^2 – 7x + 12 = 0`
B ) `y^2 – 9y + 20 = 0`

Options

A. `X gt Y`
B. `X ge Y`
C. `X lt Y`
D. X = Y or No relation can be established

Answer

D

Explanation

A) `(x+1)^2 = 12^2`
B) `y^2+2y-143=0`
`rArr y^2+13y - 11y - 143=0`
`rArr y(y+13) - 11(y+13) =0`
`rArr` (y+13)(y-11)=0
y=11, -13
So, no relation can be established.
