Q1. In a triangle ABC, angle A is greater than angle B. If the measurese of angle A and B satisfy the equation 3 sinx - 4sin3 x- k = 0, 0 < k < 1, then the measure of angle C is


(a) `pi/3`


(b) `Pi``Pi/2`


(b) `(2Pi)/3`


(d) `(5Pi)/6`


Q2. If `alpha` ,`beta`   are roots of x2 + px + q = 0 and `alpha` 4 ,`beta` 4 are the roots of x2 - rx + s = 0, then the equation x2 - 4qx + 2q2 - r = 0 has always
