Correct Answer - Option 4 : 3

**Given:**

The average of 6, 14, 25, x, 13 and 35 is 16

**Formula used:**

Average = Sum of observation/Number of observation

**Calculation:**

According to the question,

Average = Sum of observation/Number of observation

⇒ (6 + 14 + 25 + x + 13 + 35)/6 = 16

⇒ 93 + x = 16 × 6

⇒ x = 96 – 93

⇒ 3

**∴ The value of x is 3.**
