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

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.

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

= 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?

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

@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.
