Banker's Discount Questions

FACTS  AND  FORMULAE  FOR  BANKER'S  DISCOUNT  QUESTIONS

 

 

Banker's Discount : 

Suppose a merchant 'A' buys goods worth, say Rs. 10,000 from another merchant 'B' at a credit of say 5 months.Then, B prepares a bill, called the bill of exchange. A signs this bill and allows B to withdraw the amount from his bank account after exactly 5 months.

 

The date exactly after 5 months is called nominally due date. Three days (known as grace days) are added to it to get a date, known as legally due date.

 

Suppose B wants to have the money before the legally due date. Then he can have the money from the banker or a broker, who deducts S.I on the face value (i.e., Rs. 10,000 in this case) for the period from the date on which the bill was discounted (i.e , paid by the banker) and the legally due date. This amount is known as Banker's Discount (B.D) Thus, B.D is the S.I on the face value for the period from the date on which the bill was discounted and the legally due date.

 

Banker's Gain (B.G) = (B.D) - (T.D) for the unexpired time.

 

Note : When the date of the bill is not given, grace days are not to be added.

 

IMPORTANT FORMULAE

1. B.D = S.I on bill for unexpired time

 

2. B.G = (B.D) - (T.D) = S.I  on T.D=T.D2P.W

 

 

 

3. T.D=P.W×B.G

 

 

4. B.D=Amount×Rate×Time100

 

5. T.D=Amount×Rate×Time100+Rate×Time

 

6. Amount=B.D×T.DB.D-T.D

 

7. T.D=B.G×100Rate×Time

Q:

If the discount on Rs. 498 at 5% simple interest is Rs.18, when is the sum due?

A) 8 months B) 11 months
C) 10 months D) 9 months
 
Answer & Explanation Answer: D) 9 months

Explanation:

F = Rs. 498

TD = Rs. 18

PW = F - TD = 498 - 18 = Rs. 480

R = 5%

 

TD=PW×TR100

 

18=480×T×5100

 

=> T = 3/4 years = 9 months
