Five Years Ago The Average Age Of A Family Of Six Members Was 20 Years. A Baby Is Born And Now The Average Age Is 22 Years. How Old Is The Baby At Present ?

Answer»

Lets assume the age of all the 6 people = 20 YEARS.

After 5 years i.e. now their ages will be 25 years.

TOTAL age of all the 6 will be = 25*6 = 150

Including baby's age, AVG is 22 years

LET x be the age of baby.

(150+x)/7 = 22

=> x = 4 years.
