Answer:
Accounting rate of return = 6.67%
Step-by-step explanation:
The accounting rate of return (ARR) is the proportion of the average investment that is earned as profit.
ARR = average operating income/ Average investment
Average income =( 55,000 + 40,000 + 35,000 + 30,000)/4=40,000
Average investment = initial cost + salvage value/2
= 1,000,000 + 200,000/2 = 600,000
ARR = 40,000/600,000 × 100= 6.67
Accounting rate of return = 6.67%
