Question

I in Find the amount when the principal is a 5000 and the interset is rs 300​

Answer 1

ANSWER :

When the principal is Rs. 5000 and the interset is Rs. 300, then the amount will be Rs. 5300.

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

SOLUTION :

✪ Given :-

• Principal, P = Rs. 5000

• Interest, I = Rs. 300

✪ To Find :-

• The Amount, A = ?

✪ Calculation of Amount :-

• Amount = Principal + Interest

$\: \: \: \: \large{ \sf{ \therefore \: \: A = P + I }} \\ \\ \large{ \sf{ \implies \: A = Rs. \: 5000 + Rs. \: 300}} \\ \\ \large{ \sf{ \implies \: A = Rs. \: 5300}} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

• Hence, the amount = Rs. 5300.

✪ Interest :-

• When a person borrows a sum of money from another person or bank or any other financial institutions for a period, on the expiry of that period, the person (borrower) has to repay his debg by paying some extra money along with the original sum of money. The extra sum of money is known as Interest.

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

✪ Types of Interest :-

• [1] Simple Interest

• [2] Compound Interest

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

✪ Simple Interest :-

• When the interest is calculated on the initial sum of money borrowed throughout the specified period, then the interest obtained is known as Simple Interest.

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

✪ Compound Interest :-

• When the interest that falls due at the end of a specified time period is added to the principal and the amount so obtained becomes the principal for calculating interest for the subsequent period and the process goes on, thus the interests obtained is knowns as Compound Interest.

$\underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

✪ Formluas :-

If,

• Principal = P

• Rate of Interest = r

• Period of time = n

• Amount = A

• Interest = I

• Simple Interest = S.I.

• Compound Interest = C.I.

Then,

❖ Formula for Calculating Simple Interest :

$\: \: \: \: \: \bigstar \: \: \: \: \: \boxed{\large{ \rm{ \: \: S.I. = \dfrac{P \times r \times n}{100} \: \: }}}$

❖ Formula for Calculating Compound Interest :

$\: \: \: \: \: \bigstar \: \: \: \: \:\boxed{\large{ \rm{ \: \: C.I. = P \: [(1 + \frac{r}{100}) {}^{n} - 1 ] \: \: }}}$

❖ Formula for Calculating Amount of C.I. :

$\: \: \: \: \: \bigstar \: \: \: \: \:\boxed{\large{ \rm{ \: \:A = P \: (1 + \dfrac{r}{100} ) {}^{n} \: \: }}}$

❖ Formula for Calculating Amount when Principal and Amount of interest is given :
