Question
In the question, two equations I and II are given. You
have to solve both the equations to establish the correct relation between 'p' and 'q' and choose the correct option. I. p2 – 20p + 96 = 0 II. q2 – 23q + 132 = 0Solution
ATQ, From I: p2 – 20p + 96 = 0 p2 – 12p – 8p + 96 = 0 p(p – 12) – 8(p – 12) = 0 (p – 12)(p – 8) = 0 p = 12, 8 From II: q2 – 23q + 132 = 0 q2 – 12q – 11q + 132 = 0 q(q – 12) – 11(q – 12) = 0 (q – 12)(q – 11) = 0 q = 12, 11 So, no relation can be established between p and q.
