Answer:
3 years
Step-by-step explanation:
let the time period be n
here it is compounded annually
so formula is amount =principal (1+r/100)^n
or,6480=3750 (1+20/100)^n
or, 648/375=(120/100)^n
or, (6*6*6*3)/(5*5*5*3)= (6/5)^n
or, (6*6*6)/(5*5*5)=(6/5)^n
or, (6/5)^3= (6/5)^n
or, n= 3
so the required time is 3 yrs
