• A. 110
  
• B. 120
  
• C. 130
  
• D. 140
  

Hint:

For averages, sum all values and divide by the number of terms.

Answer 1

The Correct Option is B

- Step 1: Extract Product A's sales. Years: 100, 120, 140.
- Step 2: Calculate total. $100 + 120 = 220$, $220 + 140 = 360$.
- Step 3: Compute average. $360 \div 3 = 120$.
- Step 4: Verify. Recalculate: $100 + 120 + 140 = 360$, $\frac{360}{3} = 120$.
- Step 5: Compare with options. Options: (1) 110, (2) 120, (3) 130, (4) 140. Matches 120.
- Step 6: Conclusion. Option (2) is correct.
