GMAT Critical Reasoning (CR) | Re: The average hourly wage of television assemblers in Vernland

Borodia will be referred as B and Vernlandian as V
For Telivision assemblers:
1.hourly wage in V << hourly wage in B
2.Borodia dropped all tariffs on V televisions three years ago.

3.No of televisions sold in B =constant

Which can be written as
In Borodia:
3(a) No of TV (assembled in B) + No of TV (assembled in V) = No Change

4.number of television assemblers in B wentdown.

Now point 4 sates that number of television assemblers in B went down.
This will imply that if productivity of assemblers in B has not gone up then number of telivision assembled at B will go down.
