Question

the difference between the compounds interest and simple interest on certain sum at 3% p.a for 3 year is rs27.27what is the sum

Answer 1

Let the sum be Rs.x. then S.I.=(x*3*3 / 100) = 9x/100
C.I = [x(1+3/100)^3 -x] = 9727x/100000
9727x/100000 - 9x/100 = 27.27
=> 2727x/100000 = 27.27
=> x = 10000
