Answer: B official key
Approach: Average = sum of the four quarterly values ÷ 4.
Solution:
Product B: Q1 = 30, Q2 = 50, Q3 = 65, Q4 = 75 (in '000s).
Sum = 30 + 50 + 65 + 75 = 220.
Average = 220/4 = 55.
Why the other options are wrong:
A (50) – Q2 value only.
C (60), D (65) – read another product or a single quarter.
E (52.5) – arithmetic slip.
Cetking shortcut: Pair the ends: (30 + 75) + (50 + 65) = 105 + 115 = 220.
Answer: B
