Question

find the rate of interest in following Principal 2500 SI 1500 time 4 year​

Answer 1

Answer:

15 is the correct answer

Answer 2

➤ Given :-

Principle :- ₹ 2500

Simple Interest :- ₹ 1500

Time :- 4 year

➤ To Find :-

Rate of interest for the given sum….…

➤ Formula required :-

$\large \dashrightarrow \orange{ \boxed{ \tt \gray{ \frac{SI \times 100}{P \times T } }}}$

➤ Solution :-

Rate of interest :-

$\tt \longrightarrow \dfrac{1500 \times 100}{2500 \times 4}$

$\tt \longrightarrow \dfrac{1500 \times \cancel{100}}{ \cancel{2500} \times 4} = \dfrac{1500 \times 1}{25 \times 4}$

$\tt \longrightarrow \dfrac{ \cancel{1500} \times 1}{25 \times \cancel{4}} = \dfrac{375 \times 1}{25 \times 1} = \dfrac{375}{25}$

$\tt \longrightarrow \cancel \dfrac{375}{25} = \dfrac{15}{1} = \boxed { \tt15 \bf\%}$

$\Huge\therefore$The rate of interest on the given sum is 15 $\bf\%$.

Simple Interest :- $\boxed{\tt \dfrac{P \times R \times T}{100} }$

Principle :- $\boxed{\tt \dfrac{SI \times 100 }{R \times T} }$

Time :- $\boxed{\tt \dfrac{SI \times 100 }{P \times R} }$
