Again 20% replaced by water =>80*20/100=16
80-16=64
now 64 litre milk is available
Again 20% replaced by water =>64*20/100=12.8
64-12.8=51.2

First Race=x
Second Race= x+6
Total = Rs. 68
x+(x+6)=68
2x+6=68
2x=68-6
2x=62
x=62/2
x=31
First race=Rs. 31
Second race= 31+6= Rs. 37
4 more in second race= 37+4= Rs. 41
