What would be the value of security which will pay you Rs. 10000, 11000, 13000, 14000, 15000 in next 5 years . Prevailing interest rate is 11%.

I will assume that the given amounts correspond to payouts at the end of year 1, year 2, etc

present value = 1000(1.11)^-1 +11000(1.11)^-2 + ... + 15000(1.11)^-5
= ...
