T-Bills: Consider a 91-day T-bill. Assume that Rs. 100 is the real value, commonly known as the PAR value. You have received this T-bill for less than its face value, which is let's say Rs. 98. You will receive Rs. 100 back after 91 days, thus making a return of Rs. 2.
Government Bonds: The interest on government bonds is paid semi-annually and has a long-term maturity. Each bond that is issued has its own name or symbol. Everything you need to know is included in the symbol. For instance, this sign is 6.67GS2035, 6.67-Annual Interest, GS-Type Government Securities (GS), and 2035-Maturity of the bond.
