:Consider the following two investment projects

$\backslash$table$[[\backslash$table$[[$Investment B$],[$end of year$],[$cash flows$]],\backslash$table$[[$Investment A$],[$end of year$],[$cash flows$]],$Year$],[100000,250000,2001],[900000,400000,2002],[300000,410000,2003],[700000,650000,2004]]$

Both projects require an investment of $900000$ at the end of $2000.$ The required rate of return for both projects is $9\%$
