Question

What is the compound interest on 8000 rupees at 20% p. a. for 2 years if the interest is calculated half yearly?​

Answer 1

P=8000, R=20p.c.p.a, N=years

A=

$p(1 + r) n\\ 100$

A=

$8000(1 + 20)2 \\ 100$

A=

$8000(120)2 \\ 100$

A=

$8000 \times 14400 \\ 10000$

A=

$116200 \\ 10$

A=

$11620$

C.I =A-P=

$11620 - 8000$

C.I=

$3620$

$p \times i \times n$

$8000 \times 3620 \times 2$

ans=

$5792.00$
