11 out of the 34 who prefer chemistry are girls.
What percentage of the students prefer biology?
.

43%

Step-by-step explanation:

There are 39 girls. 21 of them like biology. 11 out of 34 who like chemistry are girls.

No. of girls who prefer biology = 21

There are (100-39) boys. 16 of them like physics. (34-11) of them like chemistry.

No. of boys who prefer biology = 100-39-16-34+11

                                                    = 22

Percentage of students who prefer biology = × 100%

                                                                        = × 100%

                                                                        = 43%
