Answer 1

➤ Given :-

Principle :- ₹ 25000

Time :- 4 years

Rate of interest :- 9%

➤ To Find :-

Simple Interest and Total amount on the given sum..........

➤ Formulas required :-

$\dashrightarrow \tt \large \orange{ \boxed{ \tt \gray{ \dfrac{P \times R \times T }{100} }}}$

$\dashrightarrow \tt \large \orange{ \boxed{ \tt \gray{Simple \: Intrest + Principle}}}$

➤ Solution :-

Simple Interest :-

$\tt \longrightarrow \dfrac{25000 \times 4 \times 9}{100}$

$\tt \longrightarrow \dfrac{ \cancel{25000} \times 4 \times 9}{ \cancel{100}} = 250 \times 4 \times 9$

$\tt \longrightarrow₹9000$

Now,

Total amount :-

$\tt \longrightarrow25000 + 9000$

$\tt \longrightarrow₹34000$

$\Huge\therefore$The Simple Interest is ₹ 9000 and Total Amount is ₹ 34000.
