Question

principal = 4200 rate of interest = 7% time = 3 years calculate interest​

Answer 1

Given:

Principal(P)=1500

Rate of interest(r)=2%

Number of years=2(semiannually)

Formula:

Amount(A)=P(1+

100

r

)

2

⇒A=1500(1+

100

2

)

2

⇒A=1500×(1.2)

2

⇒A=2160

Compound Interest=A−P

=2160−1500

=660

Therefore, compound interest=660

Answer 2

Answer:

$interest = \frac{4200 \times 7 \times 3}{100}$

$42 \times 7 \times 3 =$

$interest = 882rs.$
