let it's compound interest rate is r%
then
7350=Sum(1+(r/100))² (1)
8575=sum(1+r/100)³ (2)
divide 1/2
then r/100 +1=1.1666
so r=16.66
put r in equation 1
7350=sum(1.166)²
sum=5400
so sum=5400
then
7350=Sum(1+(r/100))² (1)
8575=sum(1+r/100)³ (2)
divide 1/2
then r/100 +1=1.1666
so r=16.66
put r in equation 1
7350=sum(1.166)²
sum=5400
so sum=5400
