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)
