Answer» Correct Answer - Option 1 : 31 Given: Average age of 10 people in a village = 40 years Formula Used: Average Age of people in a group = Total of the age of all the people/Total number of people in the group Calculation: The total of age of all the 10 people in the village = 40 × 10 = 400 ∵ The average age increased by 1 year, the new average age = 40 + 1 = 41 Total number of people now = 10 – 1 = 9 Hence the total age of all the remaining 9 people now = 41 × 9 = 369 So, the age of the person deceased = 400 - 369 = 31 years ∴ The age of the deceased person is 31 years

Answer» Correct Answer - Option 1 : 31

Given:

Average age of 10 people in a village = 40 years

Formula Used:

Average Age of people in a group = Total of the age of all the people/Total number of people in the group

Calculation:

The total of age of all the 10 people in the village = 40 × 10 = 400

∵ The average age increased by 1 year, the new average age = 40 + 1 = 41

Total number of people now = 10 – 1 = 9

Hence the total age of all the remaining 9 people now = 41 × 9 = 369

So, the age of the person deceased = 400 - 369 = 31 years

∴ The age of the deceased person is 31 years
