Question

Today, the sum of Alex's age and Maria's age is 54. 7 years ago Maria was 7 times older than Alex.

Part A: Enter Alex's age today.
Part B: Enter Maria's age today

Answer 1

7 years ago, the sum of their ages is 54 - 7 x 2 = 40

7 years ago, Alex's age was 40 : (7+1) x 7 = 35 years old (so Alex's age today is 42)

And Maria's age today is 54-42 = 12
