How to get 4 years? Please anyone explain.

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.

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

Formulae
T= S.I *100÷P*R derives from S.I= PRT/100.
here SI is 81.
And P is 450.
T= S.I *100÷P*R derives from S.I= PRT/100.
here SI is 81.
And P is 450.

Simple interest formula.
S.I=(PxRxT)/100 ---------------> (1)
where s.i =simple interest
R=rate %
P=sum or principal
T=year.
Amount = principal + simple interest
A = P + S.I ------------> (2).
From the question.
S.I = 81
Amount =450
R=4,5% P=?
A = P + S.I -----> (2)
450 = P + 81
p=450 - 81 =369 i.e :- P =369
And now using eq(1)
S.I =(P x R xT) / 100.............(1)
81=(369 x 4.5 x T) / 100
T= (81 x 100)/369 x 4.5
T= 4 years.

81=(369 x 4.5 x T) / 100
T= (81 x 100)/369 x 4.5
T= 4 years.

81 = 450 * 4.5*time/100.
81*100= 450 * 4.5 * time.
8100 = 2025 * time.
Time = 8100/2025 = 4 year.
81*100= 450 * 4.5 * time.
8100 = 2025 * time.
Time = 8100/2025 = 4 year.
