Answer:
135 %
Step-by-step explanation:
Given that,
The selling price of T.V. set in the U.S. = $400
The Tariff imposed on T.V. sets = 30%
The Tariff on its imported components = 10%
To find,
The effective rate of protection gained from tariff = ?
Method:
As we know
Effective rate of protection
= tariff on finished imported good + cost/price of its components * (tariff on imported good - tariff on components imported)/(price of final good - price of its components)
So, by putting the given values in above formulae;
= 40% + 80% of 400 * (40% - 10 %)/(400 - 80% of 400)
= 40 + 320 * (30)/(400 - 320)
= 360 * 30/(80)
= 360 * 30/80
= 135%
