Question

find the interest if principal is rs 4178 and amount is rs 4500​

Answer 1

Answer:

Amount(A)=Rs.4500

Rate(R)=20%

Time(T)=5years

Let Principal (P) =Rs.100

Then S.I.=

100

PRT

=

100

100×20×5

=Rs.100

and amount = P + S.I. =Rs.100+Rs.100=Rs.200

If amount is Rs.200 then Principal =Rs.100

and if amount is Rs.4500 then principal

=

200

100

×4500

=Rs.2250
