Question

I. ` x^(2) - 10x+24 = 0`
II. `y^(2) - 9y + 20 = 0`
A. if ` x gt y`
B. if `x ge y`
C. if ` x lt y`
D. if ` x le y`

Answer 1

Correct Answer - B
I. ` x^(2) - 10x+ 24 = 0`
` rArr x^(2) - 6x - 4x + 24 = 0`
` rArr x(x-6) - 4(x-6)= 0`
` rArr (x - 4) (x - 6) = 0`
` :. X = 4 or 6`
II. ` y^(2) - 9y+20 = 0`
` rArr y^(2) - 5y-4y+ 20 = 0`
` rArr y(y-5) - 4 ( y - 5) = 0`
` rArr (y-4) (y - 5) = 0`
` :. y = 4 or 5`
` :. x ge y`
