Mark-Up
Mark-up is difference in retail price and the cost price, that is
R = C + M
Where R = retail price
C = cost price
M = mark-up
Markdown
Mark down is decrease in the selling price. It is the difference in the old retail price and the new retail; that is ,
MD = OP - NP
Where MD = markdown
OP = old retail price
NP = new retail price

SiMpLe InTeReSt.....
The word interest originates from Latin word intereo, which means ‘to be lost’. Interest is then developed from the concept that lending money results in loss to the lender. The word usury is usually associated with lending at an excessive rate.
...Simple Interest Formula...

I=Prt
Where I = simple interest
P = principal
r = rate of simple interest
t = time or term in years
Where I = simple interest
P = principal
r = rate of simple interest
t = time or term in years
...Simple Amount Formula...
The simple amount is the sum of the original principal and the interest earned. the simple amount formula is given
S = P(1 + rt)
S = simple interest

- exact time - it is the exact number of days between two given dates.
- approximate time - it assumes a month has 30 days in the calculation of number of days between two given dates.
- ordinary simple interest - in calculating ordinary simple interest, we use a 360 day a year.
- exact simple interest - this uses a 365/366 day year for interest computation.
...Present Value...
The present value is the value in today’s money of a sum o money to be received in the future. Hence from the formula
S = P (1 + rt)
We find P to find the present value, that is
P = S (1 + rt)ˉ¹
