Answer:
The sum of the present age of Juan and Maria is 32 years.
Step-by-step explanation:
Maria's age is three times Juan's age. In 7 years the sum of their ages will be 46 years. The sum of the current ages of Juan and Maria is
Let the Juan's present age is p.
Maria's present age is 3 p.
After 7 years,
Juan's age = p + 7
Maria's age = 3 p + 7
According to the question
p + 7 + 3 p + 7 = 46
4 p + 14 = 46
4 p = 32
p = 8
So, the present age of Juan is 8 years and Maria is 24 years, the sum is 8 + 24 = 32.
