Promissory Note

do you know what is promissory note?

A promissory note is a written promise made by one person or party to repay a loan or debt on a specified future date to another person or party.
The main features of a promissory note are as follows:
-Maker
The maker is the person that signs the note

-Payee
The payee is the person to whom the payment is to be made

-Date of the note
Is the date on which the note is made

-Term of the note
Is the length of time until the note is due for payment

-Face value
Is the amount stated on the note

-Maturity value
Is the total sum of money which the payee will receive on the maturity date

-Maturity date
Is the date on which the maturity value is due

Single Discount Equivalent

Those are the formula

r = 1 – r( 1- r1) (1 – r2) (1 – r3)

Example:

1) A car is advertised at RM50000 less 20%, 10% and 5%. Find
(a) the single trade equivalent
(b) the net price

From r = 1 – r( 1- r1) (1 – r2) (1 – r3), we get

(a) singe discount equivalent = 1- ( 1 – 0.20 ) ( 1- 0.10 ) ( 1 – 0.05 )
= 1 - ( 0.80 ) ( 0.90 ) ( 0.95 )
= 1 – 0.84
= 0.316
= 31.6%
(b) From NP = L(1-r), we get
= 50000 ( 1 – 31.6% )
= RM 34200

2) Find the single discount equivalent of 20% and 3.5%.

From r = 1 – r( 1- r1) (1 – r2) (1 – r3), we get
r = 1 ( 1 – 20% ) ( 1- 3.5% )
=0.772
=77.2%

On 30-7-2008,our beloved lecturer teach us how to calculate
the net price for a chain discount...

These Are The Formula To Calculate The Net Price For A Chain Discount

NP = L(1-r1)(1-r2)(1-r3)

Examples:
1) A television set with a catalog price of RM3000 is offered a
chain discount of 30%, 10% and 5%. Calculate the net price.

From NP = L(1-r1)(1-r2)(1-r3), we get
= 3000 ( 1 – 30%) ( 1 – 10%) ( 1 – 5%)
= 3000( 0.7 ) ( 0.9 ) ( 0.75 )
= RM 1417.50

2) A sewing machine is advertised at RM2030 less 40% and 12%

From NP = L(1-r1)(1-r2)(1-r3), we get
= 2030 ( 1 – 40% ) ( 1- 12% )
= 2030 ( 0.6 ) ( 0.88 )
= RM 1071.84

Hii all...

welcome all...
this is my first time creating a blog...
i hope with this blog i will get more information
about business math...
