Answer 1

Answer:

10% per annum. How much will

she pay to her after 3 years? Also calculate the interest paid on the 6980

Answer 2

➤ Given :-

Principle :- ₹ 4600

Time :- 3 years

Rate of interest :- 10%

➤ To Find :-

Simple Interest and total amount of the given sum

➤ Formula required :-

Simple Interest :-

${\large \tt \dashrightarrow \orange{\boxed{\tt \gray{\dfrac{P \times R \times T}{100}}}}}$

Total Amount :-

${\large \tt \dashrightarrow \orange{\boxed{\tt \gray{Simple \: Interest + Principle}}}}$

➤ Solution :-

First, we should find the simple interest by using the first formula given above, then we should find the total amount by adding Simple Interest to the principle i.e, the second formula given.

Simple Interest :-

${\tt \longrightarrow \dfrac{4600 \times 10 \times 3}{100}}$

${\tt \longrightarrow \dfrac{ \cancel{4600} \times 10 \times 3}{ \cancel{100}} = \boxed{\tt 46 \times 10 \times 3}}$

${\tt \longrightarrow 46 \times 30 = \boxed{\tt Rs \: \: 1380}}$

Now,

Total Amount :-

${\tt \longrightarrow 1380 + 4600}$

${\tt \longrightarrow Rs \: \: 5980}$

$\Huge\therefore$ The simple interest is ₹ 1380 and the total amount is ₹ 5980.
