Let p= 100%

r=8% because half early and t= 2yr...

c.i= 1st yr=8 and

2nd yr c.i.=8+ 8×8/100= 8+.64


,difference=(8-8+ .64 )=.64 but given 56; .64___56;   1___87.5;.  100___8750 ans.

Rate of interest = 8% per halfyear
Time = 2 half years
Difference of interests = $\frac{PR^{2}}{100}$

56 = $\frac{P\times (8)^{2}}{(100)^{2}}$

P = $\frac{56\times 10000}{64}$

= 8750
