quality answer required

Answer 1

Answer:

$\sf\bold{\red{Formula :-}}$

➲ Simple Interest (S.I) :-

$\implies$ $\sf\bold{\pink{S.I =\: \dfrac{Prt}{100}}}$

➲ Principal (P) :-

$\implies$ $\sf\bold{\pink{P =\: \dfrac{S.I \times 100}{rt}}}$

➲ Rate of Interest (r%) :-

$\implies$ $\sf\bold{\pink{r\% =\: \dfrac{S.I \times 100}{Pt}}}$

➲ Time (t) :-

$\implies$ $\sf\bold{\pink{t =\: \dfrac{S.I \times 100}{Pr}}}$

where,

• S.I = Simple Interest
• P = Principal
• r% = Rate of Interest
• t = Time

_______________________________________

Extra Information :-

• Principal is the amount which is lended or deposited.
• Interest is the excess money over the principal.

➭ Formula for Amount :

$\implies \sf\bold{\pink{Amount =\: Simple\: Interest\: +\: Principal}}$

Answer 2

${\longrightarrow \boxed{\sf Simple \: Interest = \dfrac{P \times R \times}{100}}}$

${\longrightarrow \boxed{\sf Principal = \dfrac{SI \times 100}{R \times T}}}$

${\longrightarrow \boxed{\sf Rate \: of \: Interest = \dfrac{SI \times 100}{P \times T}}}$

${\longrightarrow \boxed{\sf Time = \dfrac{SI \times 100}{P \times R}}}$
