Answer 1

Answer:

22

Step-by-step explanation:

No of Students in the class= 45.

No of Students passed in Paper I = 23

No of Students passed in Paper I but not II = 15

Assuming that the 15 students who passed Paper I but not II is covered in the above category,

1) The students passed in both papers = 23 - 15 = 8.

2) The no of Students passed in Paper II but not Paper I= 45 - 23 = 22.
