Question

what sum invested at 4%p.a. compounded semi annually and amount to 7803 at the end of one year ​

Answer 1

Answer:

7500 Rs.

Let the sum be P.

As, the interest is compounded half-yearly,

∴ R = 2%, T = 2 half years

A=p(1+r/100)^n

7803=p(1+2/100)²

7803=p(1+1/100)²

p=7803×50×50/51×51

p=7500
