In each of these questions , two equations (I) and (II ) are given . You have to solve both the equations and give answer .

A x
B x>y
C x≤y
D x≥y

Correct Answer: x

(i) 39x2 - 31x - 28 = 0⇒39x2  - 52x  + 21x  - 28 = 0⇒13x(3x - 4)  +  7(3x - 4) = 0⇒(3x - 4)(13x + 7) = 0.'. x  = 43,  - 713(ii) y2 - 25y + 114 = 0⇒y2 - 25y  + 144  = 0⇒y2 - 19y - 6y + 114 = 0⇒y(y - 19) - 6(y - 19) = 0⇒(y - 19)(y - 6) = 0.'. y = 6, 19So, x
