Question

2.
3. Find the Principal when:
=s.I=2800
(a) S.I
Rate=
7 %
Time =
5 years​

Answer 1

${\bigstar}$GIVEN${\bigstar}$

• Simple interest = 2800
• Rate = 7%
• Time = 5years

${\bigstar}$SOLUTION${\bigstar}$

➠simple interest = $\frac{principal \times time \times rate}{100}$

➠principal = $\frac{si \: \times 100}{rate \: \times \: time}$

➠Principal = $\frac{2800 \times 100}{7 \times 5}$

➠principal = 400 × 20

➠$\boxed{\sf{ principal = 8000 }}$

SIMPLE INTEREST:

• simple interest paid or received over period of time is a fixed percentage of the principal amount that was borrowed or lent.

FORMULA:

$\boxed{\sf{SI = PRT ÷ 100 }}$

Answer 2

Answer:

★ GIVEN{\bigstar}★

Simple interest = 2800

Rate = 7%

Time = 5years

{\bigstar}★ SOLUTION{\bigstar}★

➠simple interest = \frac{principal \times time \times rate}{100}

100

principal×time×rate

➠principal = \frac{si \: \times 100}{rate \: \times \: time}

rate×time

si×100

➠Principal = \frac{2800 \times 100}{7 \times 5}

7×5

2800×100

➠principal = 400 × 20

➠\boxed{\sf{ principal = 8000 }}

principal=8000
