b) 27,125
c) 91,215
d) 27,152​

Answer 1

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
