We can solve this problem logically also without using SI formula.
Here the the total interest amt given for 5 years is 4016.25.
Therefore for the total interest for 1 year is 4016.25/5 = 803.25.
Therefore 803.25 is the 9% of the total sum.
If we calculate the 100% of the 803.25 we will get the the total amt.
To calculate 100%, multiple 803.25 by 100 and divide it by 9.
803.25*100/9 = 8925.
Here the the total interest amt given for 5 years is 4016.25.
Therefore for the total interest for 1 year is 4016.25/5 = 803.25.

803.25*100/9 = 8925.

S.I = P*R*T /100.

Refer important formulas in S.I @ bhaskar

Why 9 is in denominator, The formula is P.R.T/100 and here the Rate and Time is in numerator ?

I=P*N*R/100
4016.25=P*5*9
4016.25=P*45
P=4016.25/45
P=89.25*100
P=8925
4016.25=P*5*9
4016.25=P*45
P=4016.25/45
P=89.25*100
P=8925

@Jyothi absolutely right.

P.C.P.A. stands for Percent Compounded Per Annum.

too simple

S I = P*R*T /100
P = (100 x S.I)/(R x T)
P = (100 x S.I)/(R x T)
