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

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 as that;
t = (100*81)/(450*4.5),
= 8100/{450*45/10},
= 8100/2025,
= 4.
t = (100*81)/(450*4.5),
= 8100/{450*45/10},
= 8100/2025,
= 4.

= 100*81/450*4.5,
= 20*18/90,
= 36/9,
= 4 years (so simple).

SI=PTR/100
81=450*4.5*x/100
81=9*4.5
=4.05/81
=4 years
81=450*4.5*x/100
81=9*4.5
=4.05/81
=4 years

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

450*4.5% = Rs 18 per year.
To find time 81/18 = 4.5.
To find time 81/18 = 4.5.
