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.

Given
Si=81
P=450
R=4.5
T=?
We know si=PRT/100.
Therefore T=si*100/P*R,
=81*100/450*4.5,
=81*10/45*4.5,
=81*2/9*4.5,
=9*2/4.5,
=18/4.5,
=4.
Si=81
P=450
R=4.5
T=?
We know si=PRT/100.
Therefore T=si*100/P*R,
=81*100/450*4.5,
=81*10/45*4.5,
=81*2/9*4.5,
=9*2/4.5,
=18/4.5,
=4.

Answer is 4.7 because;
amount = 450,
s.i=81,
p is not given,
A=P+I.
P=379,
t=81*100/(4.5*379),
t=4.73.
amount = 450,
s.i=81,
p is not given,
A=P+I.
P=379,
t=81*100/(4.5*379),
t=4.73.

T= 100 * I/P * R.
T= 100 * 81/450 * 4.5.
T= 4 YEARS.
T= 100 * 81/450 * 4.5.
T= 4 YEARS.

@Ragu.
The steps you had done is actually like this,
=(100x81)/(450x4.5)
=(2x81)/(9x4.5)
=(2x9)/(1x4.5)
=4.
You hav taken
=(2x2)/(4.5)
bt actually 81/9 is 9 not 2.
