Answer:
20%
Explanation:
Purchase of Crane cost = $69,846
Salvage value = 0
Labor savings = $21,000 per year
Let us assume Internal rate of return = X %. At IRR, Present value of Inflows = Present value of outflows.
69,846 = 21,000/1.0X + 21,000/ 1.0X^2 + 21,000/1.0X^3 + 21,000/1.0X^4 + 21,000/1.0X^5 + 21,000/1.0X^6.
69,846 = 21,000 [1/1.0X + 1/1.0X^2 + 1/1.0X^3 + 1/1.0X^4 + 1/1.0X^5 + 1/1.0X^6]
69,846/21,000 = [1/1.0X + 1/1.0X^2 + 1/1.0X^3 + 1/1.0X^4 + 1/1.0X^5 + 1/1.0X^6]
69,846 / 21,000 = 3.326
From the given table (as attached below), period (6 of 20%) Indicates 3.326. So, the Internal rate of return = 20%.


The internal rate of return is 20%.
- The calculation is as follows:
Year Cash flows
0 -$69,846
1 $21,000
2 $21,000
3 $21,000
4 $21,000
5 $21,000
6 $21,000
Here we applied the excel formula of IRR.
