Solution

The correct option is C
7

No. of students in the class in session 2011; Class 8 Sec. A = 40

If nobody took transfer and 2 students were not promoted, number of old students = 40 - 2 = 38

No. of students in the class in Session 2012; Class 9 Sec. A = 45

No. of new students = 45 - 38 = 7 students.
