annually is 3 years

Step-by-step explanation:

Principal = Rs.15625

Amount = Rs.19683

Rate of interest = 8% = 0.08

Amount = P(1+r)^tAmount=P(1+r)

t

19683=15625(1+0.08)^t19683=15625(1+0.08)

t

\frac{19683}{15625}=1.08^t

15625

19683

=1.08

t

1.259712=1.08^t1.259712=1.08

t

1.08^3=1.08^t1.08

3

=1.08

t

So, t = 3 years

Hence The time required for Rs.15,625 to become Rs.19,683 at 8% per annum compounded annually is 3 years
