Correct Answer - Option 1 : 135 cm

**Given:**

H = {120, 135, 132, 127, 141, 155}

**Formula Used:**

Average height = Sum of all the heights/Number of members

**Calculations:**

Sum of heights of 6 members = 120 + 135 + 132 + 127 + 141 + 155

⇒ Sum of heights of 6 members = 810 cm

Number of members = 6

⇒ Average height = 810/6

⇒ Average height = 135 cm

**∴**** The average height of Akshesh’s family is 135 cm.**
