Question

find the amount and compound interest on rupees 28000 for 1 year @ 10% per annum compounded half yearly​

Answer 1

Answer:

Step-by-step explanation:

If comp half yearly

R is divided by 2

Time is multiplied by 2

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

=28000(1+5/100)^2

=28000(21/20)^2

=(28000X21X21)/20X20

=₹30870

C.I=A-P

=30870-28000=₹2870
