Question

Can you send list of formulas used in mathematics?

Answer 1

Some of the imporatnt formula are
The price, at which an article is purchased, is called its cost price, abbreviated as C.P.;
The price, at which an article is sold, is called its selling prices, abbreviated as S.P.;
If S.P. is greater than C.P., the seller is said to have a profit or gain and Gain = (S.P.) - (C.P.);
If S.P. is less than C.P., the seller is said to have incurred a loss and Loss = (C.P.) - (S.P.) ;
Loss or gain is always calculated over C.P.;

Gain % =		Gain x 100
C.P.

Loss % =		Loss x 100
C.P.

SP =		(100 + Gain %)	x C.P
100

Also,

SP =		(100 - Loss %)	x C.P.	;
100

C.P. =		100	x S.P.	;
(100 + Gain %)

similarly,

C.P. =		100	x S.P.	;
(100 - Loss %)

If an article is sold at a gain of say x%, then S.P. = (100+x)% of C.P. ;
If an article is sold at a loss of say, x% then S.P. = (100-x)% of C.P. ;
