1. Answer:5100= 62500 { ( 1+r/2×100)^2 – 1}
   

   51/625 +1 ={1+r/200)^2
   

   676/625 = {1+r/100)^2
   

   26/25 =1+ r/200
   

   1/25 =r/200
   

   200/25 =r
   

   r = 8%

   Step-by-step explanation:5100= 62500 { ( 1+r/2×100)^2 – 1}
   

   51/625 +1 ={1+r/200)^2
   

   676/625 = {1+r/100)^2
   

   26/25 =1+ r/200
   

   1/25 =r/200
   

   200/25 =r
   

   r = 8%
