**Average Age Calculation:**

To calculate the average age of Amit's family, we need to find the sum of the ages of all family members and divide it by the total number of family members.

**Step 1: Find the sum of the ages 4 years ago:**

We are given that the average age of Amit's family 4 years ago was 36 years. To find the sum of the ages 4 years ago, we can multiply the average age by the total number of family members.

Average age 4 years ago = 36 years
Number of family members = 6

Sum of ages 4 years ago = Average age × Number of family members
= 36 years × 6
= 216 years

**Step 2: Find the sum of the ages at present:**

To find the sum of the ages at present, we need to add 4 years to the sum of ages 4 years ago for each family member.

Sum of ages at present = Sum of ages 4 years ago + 4 years × Number of family members
= 216 years + 4 years × 6
= 216 years + 24 years
= 240 years

**Step 3: Find the average age at present:**

To find the average age at present, we divide the sum of ages at present by the total number of family members.

Average age at present = Sum of ages at present ÷ Number of family members
= 240 years ÷ 6
= 40 years

**Step 4: Calculate the future average age:**

We are given that a new baby was born in the family one year ago. To calculate the future average age, we need to add 4 years to the average age at present.

Future average age = Average age at present + 4 years
= 40 years + 4 years
= 44 years

So, the average age of Amit's family 4 years hence will be 44 years.
