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.

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.

Why 100 is multiplied?

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.

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

Here, p.c.p.a Indicates the rate for compound interest.

P.C.P.A. Stands for Percent "Compounded" Per Annum. Then why simple interest is given in the question?

Is it asking for principal or principal+ interest. Please tell me.

P.C.P.A is percent compound per annum. Why is it using simple interest formula?
