Question

Principle = 30,000
Time = 4 years
Rate = 30
Then find the simple interest ?​

Answer 1

INTEREST=P*T*R/100

=30000*4*30/100

=3600000/100

=36000

Explanation:

Therefore ,simple interest is 36000

Answer 2

• 
  `{\dashrightarrow \sf{Principle = Rs.30000}}`
• 
  `{\dashrightarrow \sf {Time = 4 \: years}}`
• 
  `\dashrightarrow \sf{Rate = 30\%}`
• 
  `\begin{gathered}\end{gathered}`

`\begin{gathered}{\Large{\textsf{\textbf{\underline{\underline\color{brown}{To Find:}}}}}}\end{gathered}`

• 
  `\dashrightarrow{\sf{Simple \: Interest }}`

`\begin{gathered}\end{gathered}`

`\begin{gathered}{\Large{\textsf{\textbf{\underline{\underline\color{brown}{Using Formula:}}}}}}\end{gathered}`

`\dag{\underline{\boxed{\sf{ S.I = (P * R * T)/(100)}}}}`

Where

• 
  `\dashrightarrow{\sf{S.I = Simple \: Interest }}`
• 
  `{\dashrightarrow{\sf{P = Principle }}}`
• 
  `{\dashrightarrow{\sf{ R = Rate }}}`
• 
  `{\dashrightarrow{\sf{T = Time}}}`

`\begin{gathered}\end{gathered}`

`\begin{gathered}{\Large{\textsf{\textbf{\underline{\underline\color{brown}{Solution:}}}}}}\end{gathered}`

`{\quad {: \implies{\sf{ S.I = \bf{(P * R * T)/(100)}}}}}`

Substituting the values

`{\quad {: \implies{\sf{ S.I = \bf{(30000 * 30* 4)/(100)}}}}}`

`{\quad {: \implies{\sf{ S.I = \bf{(30000 * 120)/(100)}}}}}`

`{\quad {: \implies{\sf{ S.I = \bf{(3600000)/(100)}}}}}`

`{\quad {: \implies{\sf{ S.I = \bf{\cancel{(3600000)/(100)}}}}}}`

`{\quad {: \implies{\sf{ S.I = \bf{Rs.36000}}}}}`

`{\dag{\underline{\boxed{\sf{ S.I ={Rs.36000}}}}}}`

• Henceforth,The Simple Interest is Rs.36000..
