Solution

Vamos resolver o problema passo a passo.

  1. Vamos definir as idades atuais de Vinod e Ashok.

    • Suponha que a idade atual de Vinod seja 3x3x.
    • Suponha que a idade atual de Ashok seja 4x4x.
  2. Após 5 anos, as idades de Vinod e Ashok serão:

    • Idade de Vinod: 3x+53x + 5
    • Idade de Ashok: 4x+54x + 5
  3. De acordo com o problema, após 5 anos, a razão das idades de Vinod e Ashok será 7:9. Portanto, podemos escrever a seguinte equação: 3x+54x+5=79 \frac{3x + 5}{4x + 5} = \frac{7}{9}

  4. Vamos resolver essa equação para encontrar o valor de xx: 9(3x+5)=7(4x+5) 9(3x + 5) = 7(4x + 5) 27x+45=28x+35 27x + 45 = 28x + 35

  5. Subtraindo 27x27x de ambos os lados da equação: 45=x+35 45 = x + 35

  6. Subtraindo 35 de ambos os lados da equação: 10=x 10 = x

  7. Agora que temos o valor de xx, podemos encontrar a idade atual de Ashok: 4x=4×10=40 4x = 4 \times 10 = 40

Portanto, a idade atual de Ashok é 40 anos.
