Correct Answer - Option 2 : 60

**GIven :**

Age of Raman's wife = 50 years

Age of Raman is 40% more than his wife

**Formula used :**

Average = total value of all observations/Number of observations

**Calculations :**

Raman's age = 50 + 40% of 50 = 70 years

Total sum of the age of Raman and his wife = 50 + 70 = 120 years

Average of their age = 120/2

⇒ 60 years

∴ **The average of age of Raman and his wife is 60 years**
