2 answers

Same procedure as your previous post.
Formula:-
(SI=PRT/100)
>SI-390
>P-1800
>R-5/365

390=1800*5*T/100*360(>>leave 5 days and add with the final result, its helps in easy calculation).

T=1560(and add 5 days with this result)
T=1560+5=1565.

T=1565 days,
x=4years=1460 days,
T-x=1565-1460=105 days,
105 days= 3months 5 days.

Result.:4 years 3 months & 5 days.

Final Ans-> 4 years & 3 months approx.
