for raina
principal = 5000
rate = 4%
time = 2
compound amount = p (1+r/100)^n
= 5000(1+4/100)^2
= 5000(104/100)^2
= 5000 (26/25)^2
= 5000×26/25×26/25
= 5408
for leena
p = 5000
r = 4/2 = 2%
t = 1×2 = 2 half year
C.A = 5000(1+2/100)^2
= 5000 (102/100)^2
= 5000(51/50)^2
= 5000×51/50×51/50
= 5202
difference = 5408-5202 = 206
