If x and y are inversely proportional, k=xy
                                                            =20 X 600
                                                            =12000
then y =k/x
           =12000/400
           =30
ans: y=30

X is inversely proportional to y.
So if x increases by 20 times, y should come down that much.
Hence y = 600/20 = 30
