Ethnicity

Share of ethnicity XY is 26%, which is 1/9 more than in the prewar period.

What was the share of that ethnicity in the pre-war period?

Result

p =  23.4 %

Solution:

26/100x=(1+1/9)p/100x 26=(1+1/9)p p=261+1/9 p=23.4%26/100 \cdot x = (1+1/9)p/100 \cdot x \ \\ 26= (1+1/9)p \ \\ p = \dfrac{ 26 }{ 1+1/9} \ \\ p = 23.4 \%
