3
9^2
9
27
None of these
92 × 576 ÷ (2 × √1296) = (?)^3 + √49
or, 92 × 576 / 72 = (?)^3 + 7
or, 736 - 7 = ?^3

Direction (26-30): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and given answer:
a) P< Q
b) P ≤ Q
c) P ≥ Q
d) P = Q or no relation can be established between P and Q
e) P> Q

26. Ⅰ. 9P^2 – 9P + 2 = 0
Ⅱ. 18Q^2 + 3Q = 1

a)
b)
c)
d)
e)
Ⅰ. 9P^2 – 9P + 2 = 0
Or, 9P^2 – 6P – 3P + 2 = 0
Or, (3P – 1)(3P – 2) = 0
∴ P = (1 / 3), (2 / 3)
Ⅱ. 18Q^2 + 3Q – 1 = 0
Or, 18Q^2 + 6Q – 3Q – 1 = 0
Or, (6Q – 1)(3Q + 1) = 0
∴ Q = - (1 / 3), (1 / 6)
Hence , P> Q

a)
b)
c)
d)
e)
Ⅰ. P^2 + 13P + 42 = 0
Or, P^2 + 7P + 6P + 42 = 0
Or, (P + 7)(P + 6) = 0
∴ P = -7, -6
Ⅱ. 2Q^2 + 22Q + 60 = 0
Or, Q^2 + 11Q + 30 = 0
Or, (Q + 5)(Q + 6) = 0
∴ Q = -5, -6
Hence , Q ≥ P

28. Ⅰ. 6P + 7Q = 45
Ⅱ. 2P + 3Q = 17

a)
b)
c)
d)
e)
P = 4 and Q = 3
Hence P> Q

29. Ⅰ. 3P^2 + 192 = - 48P
Ⅱ. Q^2 + 16Q + 64 = 0

a)
b)
c)
d)
e)
Ⅰ. 3P^2 + 48P + 192 = 0
Or, P^2 + 16P + 64 = 0
Or, (P + 8)^2 = 0
∴ P = -8 , -8
Ⅱ. Q^2 + 16Q + 64 = 0
Or, (Q + 8)^2 = 0
∴ Q = -8, -8
Hence , P = Q

30.Ⅰ. 15P^2 - 8P + 1 = 0
Ⅱ. 45Q^2 + 21Q = 6

a)
b)
c)
d)
e)
Ⅰ. 15P^2 – 8P + 1 = 0
Or, 15P^2 – 3P – 5P + 1 = 0
Or, (3P – 1)(5P – 1) = 0
∴ P = (1 / 3), (1 / 5)
Ⅱ. 45Q^2 + 21Q – 6 = 0
15Q^2 + 7Q – 2 = 0
Or, 15Q^2 + 10Q – 3Q – 2 = 0
Or, (5Q – 1)(3Q + 2) = 0
∴ Q = (1 / 5), - (2 / 3)
Hence , P ≥ Q
