Dear Student
when we eject 6litres out of mixture N,
the mixture will come out in the ratio of (4:11)
So, part of the milk being ejected out of N=4/15*6=8/5
So, part of the water being ejected out of the N=22-(11/15*6)=22-22/5=88/5
Thus, when this ejected mixture is added to the mixture M
So, the resultant mixture of pure milk in M=32+8/5=168/5litres
So, the resultant mixture of pure water left in N=22-22/5=88/5litres
Thus the ratio of Pure Milk(M)/Pure Water(N)=168/88=21/11
