Correct Answer: 155
Solution :
For year A, the savings = 350 – 150 = 200
For year B, the savings = 250 – 100 = 150
For year C, the savings = 200 – 150 = 50
For year D, the savings = 400 – 100 = 300
For year E, the savings = 150 – 75 = 75
The total savings over the five years = 200 + 150 + 50 + 300 + 75 = 775
Therefore, the average savings over the five years = $\frac{775}{5}$ = 155
Hence, the correct answer is 155.
