Question

find the principal of the given question.....
Ravi invest some money in bank at the rate of 4% for 3 years and the simple interest is 1140.
Find the principle​

Answer 1

➤ Given :-

Rate of interest (R) :- 4%

Time (T) :- 3 years

Simple intrest (SI) :- 1140

➤ To Find :-

Amount invested by Ravi.....

➤ Formula :-

$\large{\orange {\bf {\underline {\underline {P×R×T÷100}}}}}$

➤ Solution :-

$\longrightarrow \sf \: Principle = \frac{SI \times 100}{R \times T}$

$\longrightarrow \sf \: \frac{1140 \times 100}{3 \times 4}$

$\longrightarrow \sf \cancel \frac{114000}{12} = \frac{9500}{1} = 9500$

$\Huge\therefore$The principle amount is ₹9500.

Answer 2

Given

Rate of interest :- 4%

Time :- 3 years

Simple intrest :- 1140

We find

Amount invested by Ravi

Formula used

P × R × T ÷ 100

According to the question

$\begin{gathered}\longrightarrow \sf \: Principle = \frac{SI \times 100}{R \times T} \\\end{gathered} \\ \\ </p><p></p><p>\begin{gathered}\longrightarrow \sf \: \frac{1140 \times 100}{3 \times 4} \\\end{gathered} \\ \\ </p><p></p><p>\begin{gathered}\longrightarrow \sf \cancel \frac{114000}{12} \\ \\ \longrightarrow\frac{9500}{1} \\ \\ = 9500 \\\end{gathered} </p><p></p><p>$

So, Principal is 9500.
