Question

what sum of money will amount to RS 6655 at the rate of 10%per annum, compounded annually in 3 years?

Answer 1

given..

R = principal amount =?

c = compounded amount = 6655

n= no.of years = 3

i = rate of interest per annum = 10%

we know that c = p((1+i)^n

6625= R((1+10%)^3

6625=  R((1+0.1)^3

6625 =  R((1.1)^3

6625 =  R(1.331)

6625/1.331 =  R

4977 =R is the principal amount..

Answer 2

Answer:

6655=p(1+1/10)3.

6655×10\11×10/11×10/11

6655×1000/1331

1331×5=6655sothat ans wil be 5×1000=5000
