Question 1184489
the fathers age is 10 yrs older than his son while that of the mother was 5 yrs younger than the father.
 If the son is x years. What will be their total age in five years to come?
:
Present age
father = x+10
mother = x+10-5 = x+5
son = x
:
total age in five yrs = Father+5 + Mother+5 + son+5
t = (x+10)+5 + (x+5)+5 + x+5
t = x+15 + x+10 + x+5
t = 3x + 30
:
Obviously a step-son
