Answer:

Biology but no maths = 13

Step-by-step explanation:

No of students = 25

12 have taken maths.

8 have taken maths but not biology.

Maths + Biology = 4

Number of students taken biology = 25-12 + 4 = 17

Students who have taken biology but not maths = 17 - 4 = 13

then,

B=4

only B=25-12=13

B with M=13+4=17
