Answer: 
option (D) : 34.05% 
 Explanation: 
As per the data given in the question, 
 Computation of Simple rate of return : 
Investment = $425,000 
Depreciation = (Initial cost - salvage value) ÷ useful life 
= ($425,000 - 0) ÷ 10 
= $42,500 
Net profit = Sales revenue - cash operating expense - Depreciation 
= $527,000-$339,800-$42,500 
= $144,700 
Simple rate of return = Net Profit ÷ Investment 
= $144,700 ÷ $425,000 
= 34.05% 
Hence, option (D) is correct answer
