I am using PC Tulsian book for Financial reporting (CA final). I like to know how PVF is calculated for IRS. This problem is given in their book page 8B 10 

PVF on the basis of discount factor.

0.95681877,  0.91909895, 0.88486358.

I am not able to understand how the above figures are arrived.

With Regards
