Age Problem 1

Juan is six years older thatn Pedro. Three years hence, Pedros' age will be two third of Juans' age. Determine their ages now.

Solution:
let x be the age of Pedro
y be the age of Juan

Condition:

Juan is 6 years older than Pedro
so:
y= 6+x

Three years hence, Pedros' age will be two third of Juans' age




getting x we get x= 9

y= 6+x= 6+9= 15

Juan's age= 15
Pedro's age= 9
