Question

calculate the amount and. impound interest on rs 20000 for 1 year at 10% per annum compound half yearly
​

Answer 1

principal = 20000

time = I years = 2 half yearly ( compound half yearly)

rate of interest =10 percent = 5 percent ( compound half yearly)

amount = p ( 1+r /100)

20000(1+5/100) range to power 2

20000(21/20*21/20)

I had taken 21/20as per by taking l. c. m and two times as their was a power of 2

so ans. is 22050 that's amount

and compound interest = a-p

c. I = 2050
