Question

Find the compound interest when principal is rs 7000 rate is 5% per annum and period is 2 years ( plz do with long method not with formula).

Answer 1

si=p×r×t/100

7000×5×2/100=700

amount =700+7000=7700

Answer 2

here is your answer friend:
Given,
p=7000
r=5%p.a.
t=2years
therefore, principal for 1st year is 7000
:.Amount for the first year=PRT/100.
=7000*5*1/100
= 70*5
= £ 350.
principal for second year is 7000+350=7350
:. Amount for second year=PRT/100.
=7350*5*2/100
=£ 735.
:. compound interest =(£350+£735)
=£ 1085.

here's your formula
A=P(1+R/100) to the power t.
ok
p refers to principal
a amount
r rate
and t time.

at last compound interest=A-p(amount- principal)
ok
