Question
In the following question, read the given statement and
compare Quantity I and Quantity II on its basis. (Only quantity is to be considered) One root of the equation is 6. Where m and n are roots of the equation x2 – 16x + 63 = 0 (m < n) Quantity I : m2 + Q Quantity II : n2 + 4QSolution
m and n are roots of the equation x2 – 16x + 63 = 0 x2 – (7 + 9)x + 63 = 0 x = 7, 9 m = 7, n = 9 -Constable/1731125039-253.JPG)
=>∛ (100 + 243) = Q + 12 => 7 = Q + 12 => Q = -5 m = 7, n = 9, Q = -5 Quantity I : m2 + Q = 72 + (-5) = 44 Quantity II : n2 + 4Q = 92 + (-20) = 81 - 20 = 61 Quantity I < Quantity II
