Imagine you have two large pitchers, A and B. A contains 10 litres of wine and B contains 10 litres of water. One litre of water is removed from B and poured into A. The liquid is mixed very well. Then one litre of the mixture from A is poured into B. Which of the following statements is true?

Initially, A has  10 L wine and B has 10L water

Process 1 : When 1 L of water is poured from B to A

A now has 11L ( 10 L wine and 1L water) and B has 9L water

Process 2:  1L from A is put into B

1L of liquid from A will have the composition of 10/11L Wine and 1/11L Water

Composition of A(10L)  = $$\frac{100}{11}$$ L wine and $$\frac{10}{11}$$ L water

Composition of B(10L) = $$\frac{10}{11}$$ L wine and $$\frac{100}{11}$$ L water
