Question

The simple interest on a certain sum for 3 yrs at 10% per annum is rs. 829.50 find the sum

Answer 1

let the sum = principal =P

time =T= 3 yrs

rate of interest = R= 10%

simple interest =I= 829.50

I = PTR/100

P = (100*I)/(TR)

P =(100*829.50)/(3*10)

=82950/30

=Rs2765

Principal = P = Rs 2765
