The ratio of tax paid by Company A to that paid by Company B is not uniquely determined from your question alone, because no numerical data has been provided for either company’s tax.

In typical exam or textbook questions with this wording, you would first be given either:

  • The tax amounts of both companies (for example, Company A pays 30 lakh and Company B pays 20 lakh), or
  • Their profits and a common tax rate, or
  • A graph or table of tax payments,

and then you would compute:

Ratio of tax paid by A to B=Tax paid by ATax paid by B\text{Ratio of tax paid by A to B}=\frac{\text{Tax paid by A}}{\text{Tax paid by B}}Ratio of tax paid by A to B=Tax paid by BTax paid by A​

and simplify it to the form m:nm:nm:n. Since I don’t have the accompanying data (table, chart, or numbers) for Company A and Company B, I cannot calculate the actual ratio. If you share the specific figures or the full question statement (including any chart or table), I can compute the exact ratio step by step.
