A sample of \( 168 \) respondents of a sociological research splits into three categories according to nationality: Czech, Slovak and other. There is four times less Slovak respondents than Czech in the sample. The other nationality reported \( 85\% \) less respondents than Czech nationality. Choose the equation that represents the algebraic relation between the nationalities of the sample and leads to evaluation of the number of people of the given nationality.
\( x+4x+\frac{4x\cdot15}{100}=168 \), where \( x \) is the number of people of the Slovak nationality
\( x+\frac x4+\frac{x\cdot15}{4\cdot100}=168 \), where \( x \) is the number of people of the Slovak nationality
\( x+4x+\frac{4x\cdot85}{100}=168 \), where \( x \) is the number of people of the Slovak nationality
\( x+4x+\frac{4x\cdot15}{100}=168 \), where \( x \) is the number of people of the Czech nationality
