Solution

Vamos resolver o problema passo a passo.

  1. Identificar a idade atual do Sr. Tan e de seu filho:

    • O Sr. Tan tem 4m anos.
    • Ele é duas vezes mais velho que seu filho.
    • Portanto, a idade do filho é metade da idade do Sr. Tan, ou seja, 4m2=2m \frac{4m}{2} = 2m anos.
  2. Determinar a diferença de idade entre o Sr. Tan e seu filho:

    • A diferença de idade é 4m2m=2m 4m - 2m = 2m anos.
  3. Calcular a idade do Sr. Tan quando seu filho tiver 35 anos:

    • Quando o filho tiver 35 anos, a diferença de idade entre eles ainda será a mesma, ou seja, 2m anos.
    • Portanto, a idade do Sr. Tan será 35+2m 35 + 2m anos.

Conclusão: Quando o filho do Sr. Tan tiver 35 anos, o Sr. Tan terá 35+2m 35 + 2m anos.
