40 members

Step-by-step explanation:

If such a count is increased by 30%, the increase is found by multiplying such count by 0.30.  The new count is found by multiplying the original count by 1.30.  

Thus, the number of girls becomes 1.30(20 girls), or 26 girls, and the number of boys becomes 1.40(10 boys), or 14 boys.

Thus, the swim team has (26 + 14), or 40, members.
