1. Compound Interest - Instalments

If an amount 'P' is borrowed for 'n' years at r% per annum compounded annually, and x is the installment that is paid at the end of each year, starting from the first year, then:

$$P\ =\ \dfrac{\ x}{1+\dfrac{r}{100}}+\ \dfrac{\ x}{\left(1+\dfrac{r}{100}\right)^{^2}}+...+\ \dfrac{\ x}{\left(1+\dfrac{r}{100}\right)^{^n}}$$


$$P\ \left(1+\frac{r}{100}\right)^{n\ }=\ x\ \left(\left(1+\frac{r}{100}\right)^{n-1}+\left(1+\frac{r}{100}\right)^{n-2\ }...\ +1\right)$$

2. Consecutive Profit %

When there are two successive profits of $$x\%$$ and $$y\%$$ then the net percentage profit $$=\ \dfrac{\ x+y+xy}{100}$$.

When there is a profit of $$x\%$$ and loss of $$y\%$$ then net percentage profit or loss $$=\ \dfrac{\ x-y-xy}{100}$$

3. Simple and Compound Interest

The principal amount is P, rate of interest is R and time of loan is T

Simple Interest = $$\dfrac{P*T*R}{100}$$

Amount = Principal + Simple Interest

Compound Interest = $$ P(1+\dfrac{R}{100})^{T}$$ - P

For the same principal, positive rate of interest and time period, the compound interest on the loan is always greater than the simple interest.

4. SP - CP - Discount - Marked Price

The cost price of an article is C.P, the selling price is S.P and the marked price is M.P

Profit (Loss) = S.P – C.P

% Profit (Loss) = Profit (Loss)/C.P *100

Discount = M.P – S.P

% Discount = Discount/M.P * 100

Total increase in price due to two subsequent increases of X% and Y% is (X+Y+XY/100)%
