Question

what sum invested for 2 years compounded half yearly at the rate of 10% per annum will amount to 194481​

Answer 1

Answer:

time=2×2=4half years

rate=10/2=5%

amount= rs 194481

a= p(1+r/100)

194481=p(1+5/100)^4

194481= p(1+1/20)^4

194481=p(21/20)^4

194481=p(21/20×21/20×21/20×21/20)

194481=p(194481/160000)

194481×160000/194481=p

p=rs 160000ans
