Solution

The correct option is A
50, 50

Blue Coloured names:
Jim, Alfred, Charles, Joe, Howard, Nick.
Pink Coloured names:
Jane,Berta,Doris,Heather,Barbara,Liz.
Total names of each colour=6
Total names=12
Therefore percentage of both the coloured names= $\frac{6}{12} \times 100$ =50%
Since Liz and Berta are colored blue, whereas Howard and Joe are coloured pink,
new percentage of blue coloured names = new percentage of pink colored names = Old percentage of both the coloured names=50%
(As the exchanged number of names from both the group of coloured names is same)
