we know that formula for calculate the N value.
given data is:
S.I=81.
P=450.
R=4.5.
Formula is N=100*si/p*r.
=100*81/450*4.5.
=8100/2025.
=4.
N=4 years.

Please clarify me difference between P and I and their full form and way of usage in formula?

Rs. 450 at 4.5% per year gives 20.25 rupees.
So to get 81 we have to perform (81/20.25) = 4.
So to get 81 we have to perform (81/20.25) = 4.

In the question given amount as 450 but not sum as 450.
We know that amount = principle(or)sum + s.i.
So the ans might be 4.5.
We know that amount = principle(or)sum + s.i.
So the ans might be 4.5.

Yes @Sandhya I agree your view.
But here sum (or) principle is not given but he say that Rs450 to yield means we have to keep in mind that the amount never yield (produce) interest only the principle will (produce) interest; so the given amount is principle only.

t = ?
P = Rs.450.
S.I = 81.
R = 4.5%.
As we know : SI = P*R*T/100.
: T = S.I*100/P*R.
i.e: 81*100/450*405 = 4 yr.
P = Rs.450.
S.I = 81.
R = 4.5%.
As we know : SI = P*R*T/100.
: T = S.I*100/P*R.
i.e: 81*100/450*405 = 4 yr.

1% of 450 is 4.50.
2% of 450 is doubles the 1% 9.
4% of 450 is. 18.
0.5% of 450 is half the 1% 2.25.
Total 4.5 p.a. is: 20.25.
For 4 years: 4*20.25== 81.

Given,
S.I = 81, P = 450, R = 4.5.
T = S.I*100/P*R.
T = 81*100/450*4.5 (Cancel 100/450 with 5 and 81 with 9).
T = 9*2/4.5.
T = 18/4.5 => 180/45.
T = 4 Years.
S.I = 81, P = 450, R = 4.5.
T = S.I*100/P*R.
T = 81*100/450*4.5 (Cancel 100/450 with 5 and 81 with 9).
T = 9*2/4.5.
T = 18/4.5 => 180/45.
T = 4 Years.

Let's we gone to take an answer.
450*45*4/100*10.
So the answer came to the 81 rs.
That amount we shown in question so answer is true.
450*45*4/100*10.
So the answer came to the 81 rs.
That amount we shown in question so answer is true.
