in 1 hrs a machine will make 200 chocolates
1000 chocolates by machine b in 3 hrs
in 1 hrs machine b will make 1000/3 chocolates
in 1 hrs machine A and machine B will make chocolate 200+ 1000/3
=1600/3 chocolate
1600/3 chocolates made by machine A and B in 1 hrs
1 chocolate will made by both machine in 3/1600 hrs
2000 chocolates will be made by both machine in =2000x3/1600
