Question

Answer 1

Answer:

HELLO!!!!!!!

Step-by-step explanation

ANSWER:

Amount = ₹24,845.92

Compound interest = ₹4,845.92

EXPLANATION:

GIVEN:

Principal (P) = ₹20000

Rate of interest (r) = 7.5%

Time (n) = 3years

TO FIND:

Amount and compound interest

SOLUTION:

Amount (A) = P (1 + r/100)power n

A = 20000 (1 + 7.5/100)³

A = 20000 (1 + 0.075)³

A = 20000 (1.075)³

A = 20000 (1.242296)

Amount = ₹24,845.92

Compound interest (CI) = A - P

CI = 24,845.92 - 20000

Compound interest = ₹4,845.92

HOPE IT HELPS YOU!!

Answer 2

Step-by-step explanation:

Principal=64000

Rate=7.5%p.a

Time=3years

Where r is the rate and t is the time.

CI=64000(1+7.5/100)

3

−64000

=64000(1+75/1000)

3

−64000

=64000(1+3/40)

3

−64000

=64000(43/40)

3

−64000

=64000∗43/40∗43/40∗43/40−64000

=43∗43∗43−64000

=79507−64000

=15507

Hence CI will be 15507 rupees
