Solution:

As per the question, in the beginning
A = 0
B = 0
C = 5
D = 5

Pouring C into B
A = 0
B = 4
C = 1
D = 5

Pouring half of B into C
A = 0
B = 2
C = 3
D = 5

Pouring D into A
A = 3
B = 2
C = 3
D = 2

Pouring A into B
A = 1
B = 4
C = 3
D = 2

Pouring half of B into D
A = 1
B = 2
C = 3
D = 4

Hence we have achieved what was asked.

The competition was held on 11 November 2013. The logic is simple. In America, the dates are mentioned as Month/Day/Year and in Britain, dates are written as Day/Month/Year. But on 11 November 2013, the date and month will be the same. And thus both will write in the same manner i.e. 11/11/2013. If it would have been any other date, the evaluators would have been able to identify it.

Since Jasmine and Thibault ate equal amount, they should pay the same amount. But since that's not possible, they can decide with 'rock, paper, scissor' or an equivalent measure to determine who will pay the extra dollar. Now, let's assume tha Jasmine pays $1 extra after losing

Jasmine will pay $5, Thibault will pay $4 and Noah will pay $2.

If the pizza's cost was $11, we can simply keep the same offset and divide. Jasmine is paying 6% more, Thibault is paying 15% more and Noah is paying 27% more.
Keeping the offset same both Jasmine and Thibault will pay $5 each and Noah will pay $1.
