Hi bhagyajeet.sahu,

As the question says, if practice and jameson both increase at constant rate in 3 yrs time they both would be same.

So practice rate of increase be x courses/yr then after 3 yrs= 2000+ 3*x
similarly for jameson let rate of increase be y courses/yr then after 3 yrs= 3200+3*y

after 3 yrs both are same so 2000 + 3x = 32000 + 3y => x - y = 400

Final x and y which satisfy the criteria from the given options, they are x = 800 and y = 400.

Hope this clarifies!
