Internal rate of Return.
Lepton Industries has three potential projects, all with an initial cost of $1,900,000.
Given the discount rate and the future cash flows of each project, what are the IRRs of the three projects for Lepton Industries?

Q? R? S?
Project Q:
IRR is the rate of return that makes initial investment equal to present value of cash inflows
Initial investment = Annuity * [1 - 1 /(1 + r)n]/r
1,900,000 = 500,000 * [1 - 1 /(1 + r)5]/r
Using trial and error method i.e., after trying various values for R, lets try R as 9.91%
1,900,000 = 500,000 * [1 - 1 /(1 + 0.0991)5]/0.0991
1,900,000 = 500,000 * 3.799519
1,900,000 = 1,900,000
therefore, IRR of project Q is 9.91%
Project R:
IRR is the rate of return that makes initial investment equal to present value of cash inflows
Initial investment = Annuity * [1 - 1 /(1 + r)n]/r
1,900,000 = 600,000 * [1 - 1 /(1 + r)5]/r
Using trial and error method i.e., after trying various values for R, lets try R as 17.45%
1,900,000 = 600,000 * [1 - 1 /(1 + 0.1745)5]/0.1745
1,900,000 = 600,000 * 3.166532
1,900,000 = 1,900,000
therefore, IRR of project R is 17.45%
Project S:
IRR is the rate of return that makes initial investment equal to present value of cash inflows
1,900,000 = 1000000 / (1 + R)1 + 800000 / (1 + R)2 + 600000 / (1 + R)3 + 400000 / (1 + R)4 + 200000 / (1 + R)5
Using trial and error method i.e., after trying various values for R, lets try R as 23.32%
1,900,000 = 1000000 / (1 + 0.2332)1 + 800000 / (1 + 0.2332)2 + 600000 / (1 + 0.2332)3 + 400000 / (1 + 0.2332)4 + 200000 / (1 + 0.2332)5
1,900,000 = 1,900,000
therefore, IRR of project S is 23.32%
