SI = PRT/100.
PRINCIPAL = AMOUNT-SI (OR) SI*100/R*T.
PRINCIPAL = AMOUNT-SI (OR) SI*100/R*T.

S.I = P * R * T/100.
So, We Get T = S.I *100/P*R
T = 81 * 100/450 * 4.5,
So, T = 4 YEARS.
So, We Get T = S.I *100/P*R
T = 81 * 100/450 * 4.5,
So, T = 4 YEARS.

@Khusi.
Amount, the principal is the money which we lend for example I want to take 50 rupees from the bank so that will be loan or pricipal after 1 year the bank also want s s profit so they give a rate of interest for eg 2 pc so simple interest is prt/100 which will be 1 so at the end of the year they will have to give bank 501 rupees which is the amount.
So a=si + p.

In this question principal is given or amount is given since as we know amount = principal + simple interest ?

How P is the sum?
P is principle right. A is total amount. How it will come as years?
