Question 1: If (1/log3π) + (1/log4 π) > x, then x can be. 3. 2. π. none of these. Solution: Let y = (1/log3π) + (1/log4 π) = (log 3/log π) + (log 4/log π) = logπ 3 + logπ 4 = logπ 12 > x So 12 > πx 12 > π2 So, x = 2 Hence, option (b) is the answer. Question 2: The number of distinct solutions of the equation. in the interval [0, 2π] is. Solution:
