Correct Answer - Option 2 : 49

**Given**
Average marks of 22 students = 48

Girls who left the class scored 35 and 38 marks

One girl who joined the class score 46 marks

**Concept**

Average = Sum of all observation/ Number of observation

**Calculation**

Total marks scored by 22 students = 22 × 48

= 1056

Number of students left in the class = 22 - 2 + 1

= 21

Total marks scored by 21 students = 1056 - 35 - 38 + 46

= 1029

Average marks of 21 students = 1029/21

= 49
