Question

if the rate of interest is 30 % then what is the amount of 3000 after 50 years​

Answer 1

Answer:

48,000

Step-by-step explanation:

SI=PTR/100

SI=3000*30*50/100

  =45000

Amount= 3000+45000

            =48,000

Answer 2

➤ Given :-

Principle :- ₹3000

Rate of interest :- 30%

Time :- 50 years

$\:$

➤ To Find :-

The total amount to be paid at end of the period.

$\:$

➤ Formula required :-

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

$\:$

★ How to do :-

Here, we are given with the principle amount, the rate of interest and the time to return the money back. We should find the total amount that the person will return back at end of the period. We can use the given formula to find that. But, here we are not provided with the simple interest. So, first we should find the simple interest by multiplying the principle, rate and time and then divide by 100. The obtained answer will be the simple interest. Finally, we can add the simple interest and principle to obtain the total amount. So, let's solve!!

$\:$

➤ Solution :-

Simple Interest :-

${\tt \leadsto \dfrac{3000 \times 30 \times 50}{100}}$

${\tt \leadsto \dfrac{3000 \times 30 \times \cancel{50}}{\cancel{100}} = \dfrac{3000 \times 30 \times 1}{2}}$

${\tt \leadsto \dfrac{3000 \times \cancel{30}}{2} = \dfrac{3000 \times 15}{1}}$

${\tt \leadsto \cancel \dfrac{45000}{1} = 45000}$

$\:$

Now,

Total Amount :-

${\tt \leadsto 45000 + 3000}$

${\tt \leadsto \boxed{\tt Rs \: \: 48000}}$

$\Huge\therefore$ The total amount to be paid at end of the period is ₹48000.
