Juanico is 4 years less than half the age of Gladys. If Gladys will be 40 years old ten years from now, calculate Juanico's age 30 years from now. Give me reasons, before answering the question
If Gladys will be 40 years old ten years from now, she is 40 - 10 = 30 years old currently. Juanico is 4 years less than half the age of Gladys, meaning he is 4 years younger than 1 / 2 * 30 = 15 years. Juanico's age is 15 - 4 = 11 years. Juanico's age 30 years from now will be 30 + 11 = 41 years. So the final answer is 41.
