Simple interest = 4016.25.
Rate = 9%.
Time=5 year's.
Sum = si * 100/r.
Sum=4016.25 * 100/9 * 5,
= 401625 ÷ 45.
Sum = 8925 answer.

Here, S.i = p * n * r/100.
Ans = 401625= P * 5 * 9/100
Next step 401625 * 100/5 * 9 = p then 40162500/45 => Ans = 8925.
Ans = 401625= P * 5 * 9/100
Next step 401625 * 100/5 * 9 = p then 40162500/45 => Ans = 8925.

Why 100 is multiplied?

HERE IS AN INTERESTING TRICK:
Since, the rate is 9% for 5 years, so total SI is 45%.
Now 45% = 4016.25 so 100% = 4016.25*100/45 = 8925.
Since, the rate is 9% for 5 years, so total SI is 45%.
Now 45% = 4016.25 so 100% = 4016.25*100/45 = 8925.

5 years = 4016.25.
So, 1 years = 803.25.
Now formula, Rate % = Interest/principalx100(only for 1 years).
So, principal=803.25/9x100=8925.
Hence principal = 8925 ans=(C).
So, 1 years = 803.25.
Now formula, Rate % = Interest/principalx100(only for 1 years).
So, principal=803.25/9x100=8925.
Hence principal = 8925 ans=(C).

Hi friends! I am Vinaya.
Here we have to find d sum(p).
So formula we know is S.I=P*R*T/100;.
SO, p=S.I*100/R*T--->given S.I=4016.25 we can write it as 401625/100...R=9,T=5.
Substitute the values ...P=401625*100/100*9*5..
After calculation, we get 8925.

Total S.I-Rs4016.25.
Rate-9%
Time-5yrs
S.I.=[P*R*T/100]
So,
P=[S.I.*100/R*T]
P=[4016.25*100/9*5]
=8925 Ans.
Rate-9%
Time-5yrs
S.I.=[P*R*T/100]
So,
P=[S.I.*100/R*T]
P=[4016.25*100/9*5]
=8925 Ans.

We can also use the formula.
Simple interest =principal *rate *time all over 100.
4016.25=p*9*5/100,
4016.25=45p/100,
Then cross multiply;
45p=401625,
divid both side by 45.
p=8925.
There the sum = 8925.

A=p(1+RT/100).
A=total money, borrow,
P=lended,loan,sum,
R=rate,
T=time.
