Answer:

Hi there.. Here's the answer for your question..

Step-by-step explanation:

When the first child was born, the total age of all the family members

= (16 × 3) years

= 48 years

When the second child was born, the total age of all the family members

= (15 × 4) years

= 60 years

By the time the second child was born, each one of the 3 family members had grown by

=(60−483)=123

= 4 years

Hence, the age of eldest son when the second child was born = 4 years

When the third child was born, the total age of all the family members

= (16 × 5) years

= 80 years

By the time, the third child was born, each one of the four family members had grown by

= (80−604)

= 5 years

So, the age of the eldest son when the third child was born

= (4 + 5) years

= 9 years

When the fourth child was born, the total age of all the family members

= (15 × 6) years

= 90 years

By the time, the fourth child was born, each of the five family members had grown by

= (90−805)

= 2 years

So, the age of the eldest son when the fourth child was born

= (9 + 2) years

= 11 years

At present, the total age of all the 6 family members

= (16 × 6) years

= 96 years

By now, each one of the 6 members have grown by

= (96−906)

years

= 1 year

Hence, the present age of the eldest son

= (11 + 1) years

= 12 years.

Hope it helps you..

If any doubt ask me.

Thank you...
