Principal = Rs 5,000
Time = 1 1/2 years =\frac{3}{2}23 years
Rate of interest = 16 %
As the rate of interest is compounded half yearly
Rate of interest =  %
Time = \frac{3\times2}{2}23×2 = 3 duration
Simple interest on the period of six months i.e ,when, n=1, P= Rs 5,000,R=8% is given by the formula: = \frac{{\text{Principal} }\times{\text{ Rate of interest} }\times {\text{Time}} }{100}100Principal× Rate of interest×Time
= \frac{5000\times8\times1}{100}= 50 \times 8 =Rs 4001005000×8×1=50×8=Rs400
Amount after six months = Rs 5,000 + Rs 400 = Rs 5,400
New Principal =Rs 5,400
Rate = 8%, Time = 1 (between 6 months and 12 months)
Simple interest(6 Months to 12 Months) = \frac{5400 \times8 \times 1}{100} = 54 \times 8 = Rs4321005400×8×1=54×8=Rs432
Amount after 12 months = 5400 + 432 =Rs 5,832
Simple interest (1 year to 3/2 years) as rate = 8%, Time = 1 year
= 
Amount after 3/2 years = 5,832 + 466.56 = Rs 6,298.56
So, Compound Interest = Amount after 3/2 years - Principal
= 6,298.56 - 5,000
=Rs 1,298.56
