Solution:-
1st case = p= 4050 , A= 4576.50, t = 2years
s.i = 4576.50- 4050 = 526.50rupes
s.i = (p×t×r)/100
526.50 = (4050×2×r)/100
8100r = 52650 = r = 52650/8100
[r = 6.5%]ans
2ns case ,
given , p= 100000 , t=3 , r= 6.5%
= s.i = (100000×3×6.5)/100
= s.i = 1000×3×6.5
= s.i = 19500
simple intrest = 19500 ans

Step-by-step explanation:
1st part
r=?
i=4050
amount =4576.50
principal =4576.50-4050
=526.50
i=p*r*t/100
4050=52650*r*2/100*100
(100 because I have opened the decimal point)
r=4050*50*100/52650
= 6
1298—
7
2nd part
i=9600
p=1lakh
t=3years
r= 6
1298— =9092/7
7
i=p*r*t/100
9600=1lakh*r*3/100
r=8/25(answer)
