Answer 2

➤ Correct Question :-

Find the rate of interest in the following

Principle = 8550 ; Simple Interest = 1275 ; Time = 3 years.

➤ Given :-

Principle :- ₹ 8550

Simple Interest :- ₹ 1275

Time :- 3 years

➤ 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 :-

In the formula,

SI = Simple Interest

P = Principle

T = Time

So,

Rate of interest :-

$\tt \longrightarrow \dfrac{1275 \times 100}{8550 \times 3}$

$\tt \longrightarrow \dfrac{ \cancel{1275} \times 100}{8550 \times \cancel{3}} = \dfrac{425 \times 100}{8550 \times 1}$

$\tt \longrightarrow \dfrac{425 \times \cancel{100}}{ \cancel{8550} \times 1} = \dfrac{425 \times 2}{171 \times 1}$

$\tt \longrightarrow \dfrac{850}{171} = 4.9 \bf\%$

$\Huge\therefore$The rate of interest is 4.9$\bf\%$.

$\dashrightarrow$Some related formulas :-

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

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

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