11. After 10 years A will be twice the age of B before 10 years and now if the difference is 9 years between them then what is the age of B after 10 years.
Let present ages of A and B be x and y respectively.
According to the question
x+10 = 2(y-10) after solving we get
x-2y = -30 eq. (1)
x-y = 9 eq. (2) after solving above equation we will get there present ages as such A = 48 and B = 39.
After 10 years B will be 49 yrs
Let us take pure milk contains 100 litre
20% replaced by water =>100*20/100=20
100-20=80
now 80 litre milk is available
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
now 51.2 litre milk is available
