Answer:

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

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

Step-by-step explanation:

<h3>♨ Given :</h3>
  • Principal ( P ) = 7800 rupees
  • Annual rate of interest ( R ) = 9.5 %
  • Time ( T ) = 3 years

<h3>♨ To find :</h3>
  • Total interest ( I ) = ?
  • Total amount ( A ) = ?

<h3>✎ Finding the total interest :</h3>

\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 = <u>2</u><u>2</u><u>2</u><u>3</u> rupees.

<h3>✎ Finding the total Amount :</h3>

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

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

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

The total amount = <u>1002</u><u>3</u> rupees.

--------------------------------------------------------------

<h3>☞ Additional Info :</h3>
  • 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 ).

<h3>✑ Important Formulaes :</h3>
  • \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}

Hope I helped!

Have a wonderful time ツ

Answer:

The probability that on a given day below 6,214,323 drinks are sold is 0.8413.

Step-by-step explanation:

The provided information are:

Population mean (\mu) = 6,205,195

Population standard deviation (\sigma) = 9,120.32

Consider, <em>X</em> be the random variable that represents the number of drinks that are sold on a given that is normally distributed with the mean = 6,205,195 and standard deviation = 9,120.32.

The probability that on a given day below 6,214,323 drinks are sold can be calculated as:

P(X

It must be noted that <em>P</em>(<em>Z</em> < 1.0008) = 0.8413 has been calculated using the standard normal table.

Hence, the required probability is 0.8413.
