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
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??
