In a family, the average age of 5 children is 5 years. If the age of their father also included, the average age will be increased by 100%. Find the age of father.1). 45years2). 35years3). 39 years4). 30 years

Answer»

AVERAGE age of 5 children = 5 years

So, total sum of age of the 5 children = 25

Average age of 5 children including their father = 5 + 5 × 100/100 = 10 years

So, total sum of age of the 5 children including their father = 6 × 10 = 60 years

∴ Age of the father = 60 – 25 = 35 years
