Quick Examples
Example 1:
Find the Banker's Discount on ₹4,000 due after 2 years at 10% per annum.
BD = Amount × Rate × Time / 100
= 4000 × 10 × 2 / 100
= ₹800
Example 2:
If Banker's Discount is ₹300 and True Discount is ₹250, find Banker's Gain.
BG = BD − TD
= 300 − 250
= ₹50
Example 3:
Find the Present Worth if Amount Due is ₹2,200 and True Discount is ₹200.
PW = Amount − TD
= 2200 − 200
= ₹2000
Example 4:
Find the rate percent if Banker's Discount on ₹5,000 for 1 year is ₹400.
BD = Amount × Rate × Time / 100
400 = 5000 × R × 1 / 100
R = 8%
Example 5:
If True Discount is ₹100 and Present Worth is ₹1000, find Banker's Gain.
BG = TD² / PW
= 100² / 1000
= 10000 / 1000
= ₹10
