Question 7
Mr. Wood and Mr. Smith each have two children below 9 years old. Below shows some information about their children.
• Mike is 3 years younger than his brother.
• Royston is the oldest among the four children.
• Sean’s age is half of Mr. Wood’s child’s age.
• Jack is 1 year older than Mr. Smith’s younger child.
• Each family had only one child three years ago.
If the ages of the children are different, can you list their ages and group them according to their family? Find the sum of the ages of Mr. Wood’s children.
Age convention for this practice item: ages are distinct positive whole years from 1 to 8. In each family the younger child is under 3; the older child is at least 3 and a child now aged 3 counts as already born three years ago. Either complete allocation satisfying these conditions is accepted. Enter seven semicolon-separated fields: Mike age;Royston age;Sean age;Jack age;Wood children;Smith children;Wood age sum. Use the exact names, alphabetical order within each family, a comma between the two names, and no spaces.
