Father’s age is three years more than three times the son’s age.
After three years, father’s age will be ten years more than twice the son’s age.
What is the father’s present age.

• If present ages of father and son are F and S respectively, then
  
  F = 3S +3
  F+3 = 10 + 2*(S+3)
  3S+3 +3 = 10+2S+6
  S = 10 yrs
  F= 3+30=33 years
