Answer:
Simple accounting rate of return= 27.32%
Step-by-step explanation:
The accounting rate of return = Average annual operating income / Average investment
Annual depreciation = ( Cost - Salvage value)/No of years = (30,500 - 0 )/15
= 2033.33
Average Investment -= (Cost + scrap Value)/ 2
= (30500 + 0)/2 =15,250
Average Annual income = 6,200 - 2033.33
= 4166.67
Simple accounting rate of return =( 4,166.667/ 15,250 )× 100
= 27.32%
