Question

25 years ago,when my parents got married,their average age was 27 years. Now the average age of my family including my parents and me is 42 years. How old am I?

Answer 1

:- LETS ASSUME THE AGE OF THE PERSONS FAMILY
FATHER - x years old
MOTHER - y years old
SON - z years old

ACCORDING TO THE QUESTION 25 year ago....
((X-25)+(y-25))/2 = 27. .......(I)

Therefore we get -------- x+y = 100 ------

Now at present ..

( X+y+z )/3 = 42

Since x+y = 100
We get the present age of person or son as
Z= 26 years old ....

Hope u will understand .......
