MCQ - 168-8900

Correct Answer: C

Explanation:

Since A = B
∴ a +3 = 2a + 1

…(1)

b² + 2 = 3b

…(2)

b² – 5b = - 6

…(3)

From (1) a = 2

From (2), b² = 3b – 2

…(4)

From (3), b² = 5b – 6

…(5)

Equating the two values of b²
from (4) and (5), we get

3b – 2 = 5b – 6
⇒ 2b = 4 ⇒ b
= 2
Hence a = 2, b = 2
