Question

find the compound interest on 5000 rupees at the rate of 10%per annum compouned semi-annually for 3/2 years​

Answer 1

Principal= ₹5000

Rate= 10% p.a

Time= 3/2 years

First conversion period= PRT/100

Putting values= 5000×10×1/2/100

₹250

________________________________

Amount after 6 months ( semi annually)= 5000+250

₹5250

5250×10×1/2/100

₹262.5

________________________________

So now finding amount after 1 year= 5250+262.5

₹5512.5

________________________________

Simple interest for the third half year= 5512.5×10×1/2/100

27562.50/100

₹275.625

______________________________

Amount after 3÷2 year= 5512.5+275.625

₹5788.125

______________________________

Compound interest= Amount-Principal

5788.125-5000

₹788.125
