### Multiple IRR problem

In order to calculate IRR, you have to solve the following equation for r
-2000 + 10000/(1+r) - 10000/(1+r)^2 = 0

you will get two values (solve the quadratic equation).

Or

As a shortcut, instead of solving the above quadratic equation, you can check answers by the following calculation:

10,000 ÷ 1.38 - 10,000 ÷ 1.382 = 1995.38

And:

10,000 ÷ 3.6 - 10,000 ÷ 3.62 = 2006.17

Both discount rates give NPVs of approximately zero and thus, are IRRs.

Here the discount factors used are 1.38 (1+0.38) & 3.6 (1+2.6)

Hence the correct option is ( A )
