Question

in what time will Rs. 1000 amount will change to Rs1331 at 10% per annum

Answer 1

S.I = p*t*r/100
1331= 1000*t*10/100
1331= 100*t
1331/100=t
13.31 =t
 
time is 13.31 years

Answer 2

Answer:

Given:-

P=Rs 1000

R=10%p.a.

Time=?

Amount =Rs1331

A=P(1+R/100)^n

1331=1000(1+10/100)^n

1331/1000=(1+1/10)^n

(11/10)^3=(11/10)^n

3=n

Hence, Time=3years
