Question

Find the simple interest and the total amount after three years.

Answer 1

Answer:

$\boxed{ \sf{Total \:Interest = \underline{ 2223} \: rupees}}$

$\boxed{ \sf{Total \: Amount = \underline{10023} \: rupees}}$

Step-by-step explanation:

♨ Given :

• Principal ( P ) = 7800 rupees
• Annual rate of interest ( R ) = 9.5 %
• Time ( T ) = 3 years

♨ To find :

• Total interest ( I ) = ?
• Total amount ( A ) = ?

✎ Finding the total interest :

$\boxed{ \sf{Simple \: interest \: ( \: I\: )\: = \frac{Principal \: ( \: P \: ) \: \times \: Time \: ( \: T \: ) \: \times \: Rate \: ( \: R \: )}{100}}}$

$\longrightarrow{ \sf{ \frac{7800 \times 3 \times 9.5}{100}}}$

$\longrightarrow{ \sf{ \frac{222300}{100}}}$

$\longrightarrow{ \sf{2223 \: rupees}}$

The total interest = 2223 rupees.

✎ Finding the total Amount :

$\boxed{ \sf{Amount \: (A) = Principal \: ( \: P \: ) \: + \: Interest \: ( \: I \: )}}$

$\longrightarrow{ \sf{7800 \: rupees + 2223 \: rupees}}$

$\longrightarrow{ \sf{10023 \: rupees}}$

The total amount = 10023 rupees.

☞ Additional Info :

• Principal : The money which is borrowed or deposited is called principal ( P ).
• Interest : The additional amount of money which is paid by borrower to the lender is called Interest ( I ) .
• Time : The duration of time for which principal is deposited or borrowed is termed as time period ( T ).
• Rate : The condition under which the interest is charged is called rate ( R ).
• Amount : The sum of principal and interest is called an amount ( A ).

✑ Important Formulaes :

• $\sf{Interest \: = \frac{Principal \times Time \times Rate}{100}}$

• $\sf{Principal = \frac{Interest \: \times \: 100}{Time \times Rate}}$

• $\sf{Time = \frac{Interest \: \times \: 100}{Principal \times Rate}}$

• $\sf{Rate = \frac{Interest \: \times \: 100}{Principal \times Time}}$

• $\sf{Amount = Principal + Interest}$

• $\sf{Principal = Amount - Interest}$

• $\sf{Interest = Amount - Principal}$
