If Mike is 6 years old and twice as old as his brother, then his brother is 3 years old. When Mike is one and a half times his brother's age (1.5 * 3 = 4.5), he will be 4.5 years older than his brother. Therefore, Mike will be 6 + 4.5 = 10.5 years old when he is one and a half times his brother's age.
Mike is 12. Mary is 4. In 4 years, Mike will be 16 and Mary will be 8. So Mike will be twice as old as she is in four years.
12,4...16,8
Mary is 4 years old. [A+]
