Question

Find % profit Or loss % :-

Find the amount to be paid for
the principal ₹7500 , Time =3 years, R= 5% p. a. ​

Answer 1

Answer:

P = ₹7500

R = 5%

T = 3 years

$SI=P×R×T/100$

$SI=7500×5×3/100$

$SI=75×5×3$

$S.I. = ₹1125$

Now, for finding Amount,

A = P + I

A = 7500 + 1125

A = ₹8625

Therefore, Amount paid at the end of 3rd year = ₹8625

Here,

P = Principal

R = Rate

T = Time

S.I. = Simple interest

A = Amount

Answer 2

➤ Given :-

Principle :- ₹7500

Rate of interest :- 5%

Time :- 3 years

➤ To Find :-

Total amount to be paid at end of the time

➤ Formula required :-

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

How to do :-

Here, we are given that the principle is ₹7500 for 5% of rate of interest and time taken is 3 years. We should find the total amount of the given sum. First, we should find the simple interest by multiplying the principle, rate and time and then divide by 100 and then we should find the total amount by using the given formula.

➤ Solution :-

Simple Interest :-

${\tt \longrightarrow \dfrac{7500 \times 5 \times 3}{100}}$

${\tt \longrightarrow \dfrac{\cancel{7500} \times 5 \times 3}{\cancel{100}} = 75 \times 5 \times 3}$

${\tt \longrightarrow 75 \times 15 = \boxed{\tt 1125}}$

Total amount :-

${\tt \longrightarrow 1125 + 7500}$

${\tt \longrightarrow \boxed{\tt Rs \: \: 8625}}$

$\Huge\therefore$ The total amount of the given sum is ₹8628.
