Question

we landw thent we dowt lanow p ( A=Pleft(1+frac{r}{100}right)^{n} )
were we (cucw ( A )
G ( 578 cdot 40=Pleft(1+frac{gamma}{100}right)^{2} )
(i) ( 614.55=Pleft(1+frac{8}{100}right)^{3} )
( frac{614.55=}{100}=1.0625 )
( frac{578.40}{5}>frac{x}{100}=0.0625 )
( =1 gamma=6.250 % )

# 3993? 11. A sum of money put out at compound inter. amounts in 2 years to 578.40 and in 3 years * 614.55. Find the rate of interest. 12 (Hint: 578.40 = P(1+100) 61456 =P(+10) 614.55= P 1+- 614.55 Dividing, 578.40 =l+ 10
