Sheena is now one third of her father's age.Twelve years hence she will be half as old as her father.Find their present ages??
Answered by Reiny
Sheena's present age --- x
her dad's present age --- 3x

in 12 years:
Sheena's age = x+12
dad's age = 3x+12

x+12 = (1/2)(3x+12)
2x+24 = 3x + 12
x = 12

Shenna is pesently 12 and her dad is 36
