I should explain clearly in this.
Then time =100 * 81/450 * 4.5,
= 2 * 9/4.5,
= 18/4.5,
= 18 * 10/45,
= 18 * 2/9,
= 2 * 2,
= 4 years.
Then time =100 * 81/450 * 4.5,
= 2 * 9/4.5,
= 18/4.5,
= 18 * 10/45,
= 18 * 2/9,
= 2 * 2,
= 4 years.

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

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

The amount is 1200.
The rate of interest-4.5%,
Thus, amount /interest =si for a year.
1200/4.5--->20.25.
Now, the interest amount 81.
81/20.25===>4years.

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

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

100% = 450,
4.5%*x = 81,
X = 4.
4.5%*x = 81,
X = 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.
