Question

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

Answer 1

Hi Friend,

Let the sum be P
Simple Interest = Rs.829.50
Time = 3 years
Rate of interest = 10%

S.I = PRT/100
829.50 = P X 10 X 3 /100
82950/100 = P X 10 X 3/100
82950 = 30P
P = 2765

 The sum is Rs 2765


Hope it helps you!!

Answer 2

your time is given that means your time is 3 years and your rate is also given for 10 percent



and your S.I. Is 829.50

then you find principal



1st step :p= ?
2nd step : time =3 years
3rd step : rate =10 percent


then find your principal ....

so first you have write your S.I . formula =P×T×R/100

S.I.=p×3×10/100
so, let the principal be x

then S.I. = X × 3 × 10 /100

829.50 = X × 3 × 10 /100

82950 /100 = p × 10 × 3/100

82950 = 30 P

then the p= 2765


so, that the principal is 2765 answer.............
