Investment from year 1 to year 5 is $10,000 at 10% while investment from year 6 to 8 is $16,000 per year at 14%
Present worth is calculated as: [Investment / (1 + Rate of Interest)^Year
Present value of Investment made in 1st year = [10,000 / (1 + 0.1)^1] = 9,090.9
Present value of Investment made in 2nd year = [10,000 / (1 + 0.1)^2] = 8,264.46
Present value of Investment made in 3rd year = [10,000 / (1 + 0.1)^3] = 7,513.14
Present value of Investment made in 4th year = [10,000 / (1 + 0.1)^4] = 6,830.13
Present value of Investment made in 5th year = [10,000 / (1 + 0.1)^5] = 6,209.21
Present value of Investment made in 6th year = [16,000 / (1 + 0.14)^6] = 7,289.38
Present value of Investment made in 7th year = [16,000 / (1 + 0.14)^7] = 6,394.19
Present value of Investment made in 8th year = [16,000 / (1 + 0.14)^8] = 5,608.91
Sum of present value of all investment made in various years is 57,200.39
