Question 2 RTA is considering two options for its new office blocie High Initial Cost M & Costs = $ 4.5M / (ye) year ; Benefit = $ 11 M/year Disbenefits =$ 2M per year Life = 10 years ; Low Rise: Initial Cost= $ 54 M; M &O Costs =$ 3.5 M /year ; $ 15 Myear ; Disbenefits =$ 4.5 Mper year 20 years . Use j=11\% for both options .
Here,
High Rise | Low Rise | |
Initial Cost | $20M | $54 M |
O&M Cost | $4.5 M/ year | $3.5 M /year |
Benefit | $11 M/ year | $15M/ year |
Disbenefit | $2 M/ year | $4.5 M / year |
Life | 10 yrs | 20 years |
i | 11% |
since, initial cost of high rise is not given it is assumed to be 20 m

20-04-2040 | Year 20 | 7000000 | |
XIRR | 18.31% | 11.48% | |
From above high rise looks better but as the initial cost change the result might be different
