How can i calculate Arbitrage free value of treasury note from BAII Plus? Question 15 page 518 Reading 65 Fixed Income… Please help me if there is any alternative way to calculate rather than finding present value of all cashflows.

you have to calculate the PV of all cash flows using the corresponding discount rate dude.

so we cant use multiple discount rates on cash flows using calculator and have to find the present value of all individual cash flows separtely??

Yeh. I think you need to Store a running sum of all PVs. No automatic calc there.
