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%
