Question

Find the amount to be paid at the end of 4 years for principal = Rs.75,000 at the rate of 5% per annum​

Answer 1

Answer:

Here, Principal (P)=Rs.7,500, Rate (R)=5% p.a, Time (T)=3 years

Simple Interest =

100

P×R×T

=

100

7500×5×3

=Rs.1,125

Now, Amount = Principal + Simple Interest

=7500+1125

=Rs.8,625

Answer 2

➤ Given :-

Principle :- ₹ 75000

Rate of interest :- 5%

Time :- 4 years

➤ To Find :-

Total amount to be paid at end...........

➤ Formula required :-

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

➤ Solution :-

First, we should find the simple interest of the given sum..........

${ \tt \longrightarrow \dfrac{75000 \times 5 \times 4}{100}}$

${ \tt \longrightarrow \dfrac{ \cancel{75000} \times 5 \times 4}{ \cancel{100}} = \boxed{ \tt 750 \times 5 \times 4}}$

${\tt \longrightarrow 750 \times 20 = \boxed{ \tt 15000}}$

Now,

Total amount :-

${ \tt \longrightarrow 75000 + 15000}$

${\tt \longrightarrow \sf Rs \tt \: \: 90000}$

$\Huge\therefore$The total amount of the given sum is ₹ 90000.

Simple Interest :- ${\boxed{\tt\dfrac{P \times R \times T}{100}}}$

Principle :- ${\boxed{\tt\dfrac{SI \times 100}{R \times T}}}$

Rate of interest :- ${\boxed{\tt\dfrac{SI \times 100}{P \times T}}}$

Time :- ${\boxed{\tt\dfrac{SI \times 100}{P \times R}}}$
