Question

in how many years will a sum of 3000 at 20% per anum compounded semi anually become 3993​

Answer 1

Step-by-step explanation:

Principal = Rs 3000

rate=10% compounded half yearly

time= T half years

amount = Rs 3993

P (1+R/100)^T=A

=>3000 (1+10/100)^T=3993

=>3000 (11/10)^T=3993

=>(11/10)^T=3993/1000

=>(11/10)^T=(11/10)^3

=>T=3

Time taken is 3 half years or 1 1/2 years.
