## Challenge:

Mr. Ronald is 53 years old. He has three children, John 14 years old, Nicole 9 years old and Mark 4 years old. In how many years, the age of Mr. Ronald will become equal to the sum of his children’s age?

### The Absolute Best Book** to ****challenge your Smart Student!**

The correct answer is 13.

Mr. Ronald is 53 years old and the sum of his children is:

14 + 9 + 4 = 27

The difference of Mr. Ronald’s age and his children is:

53 – 27 = 26

Every year, one year adds to Mr. Ronald’s age and three years adds to the sum of his children’s age. The difference of this is 2 years. So, each year 2 years is subtracted from the difference of Mr. Ronal’s age and his children.

Therefore, in 13 years the difference of Mr. Ronald’s age and his children becomes zero.
