Now we are in the year 2004. The ratio of ages of my father, my
mother, and my younger brother is 12:9:1. Five years from now, my father
will be 41 years old. In what year was my younger brother born?
let my fathers age (in years) = x
my mothers age (in years ) = y
and my younger brothers age (in years ) = z
according to question,
x /z = 12/1 .......................(Ist)
After 5 Years,
my fathers age = x+5 =41
or x=41 -5 =36
hence my fathers Present age = 36 years
From Equation Ist ,
x/z =12 /1
or z= 36/12
or z = 3
Hence My Younger Brother is 3 years Old in 2004 , hence was born in 2001
Hope u Understood the Solution !!!
Please mark as best !!
