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. <hau> Idan Gladys za ta kasance shekaru 40 a cikin shekaru goma daga yanzu, tana da shekaru 40 - 10 = 30 a yanzu.
