Question 814892: Mrs. Jones is 28 years old.In 4 years she will be 3 times as older as her son. how old will each be?
Answer by FightinBlueHens(27)   (Show Source):
You can put this solution on YOUR website! Mrs. Jones is 28 years old now, so in three years she'll be 30. If, when she will be 30 she will be 3 times as old as her son, one-third of 30 is 30/3=10.
So in three years her son will be 10 years old.
Right now though, her son is 3 year's less than 10 years old, 10-3=7, so he is 7 years old right now.
