2

Step-by-step explanation:

Total 32

Doing Mathematics -29

Doing Chemistry-20

Not Doing Anything-5

Students Studying- 32-5=27

Students doing maths and both together= 29+B(both) Or B= 29-Maths

Students doing Chemistry and both together= 20+B Or B=20- Chemistry

29-Maths=20-Chemistry

Maths=Chemistry+9

Students doing Maths+Chemistry+Both together = 27

Students only doing Chemistry=29-27= 2
