Answer 1

18 months means 1 year & 6 months so
Ashok:-

we calculate 1 year amount first which is
X(1+20/100) & then we take another 6 months as 1/2 year so amount become x(1+20/100)*(1+20/100*1/2)

18 months means 3*6 months so
Geeta:-

We calculate 6 months amount first which is x(1+20/100*1/2) & then following 6 months amount will be x(1+10/100)(1+20/100*1/2) & last 6 months after amount will be x(1+10/100)(1+10/100)(1+20/100*1/2)=x(1+10/100)^3.....,.........
