Correct Answer - Option 1 : Six

**Given:**

The marks obtained in mathematics by 12 students are 35, 30, 25, 15, 20, 47, 30, 40, 45, 50, 40, 43

**Formula used:**

Average = Sum of all observation/Total number of observation

**Calculation:**

Average = (35 + 30 + 25 + 15 + 20 + 47 + 30 + 40 + 45 + 50 + 40 + 43)/12 = 420/12 = 35

Here marks 47, 40, 45, 50, 40, 43 are more than 35

Required answer = Six

**∴ Required answer is Six.**
