Question 2
In a certain year, California extracted 2/7th and Texas extracted 1/7th of all the Uranium ore extracted in the United States. If all the other states combined extracted 28 million tons that year, how many million tons did Texas extract that year?
  1. 12
  2. 7
  3. 14
  4. 5
  5. 8
The correct Answer is 7 million tons and the correct Choice is (B).

Explanatory Answer
Together, California and Texas extracted 2/7 + 1/7 = 3/7th of all the Uranium ore extracted in the country.

Therefore, all the other states extracted 1 - 3/7 = 4/7 th of all the Uranium ore extracted in the country.

The combined production of all the other states = 28 million tons.

i.e., 4/7th of total production = 28 million tons.

So, total production = (28 * 7)/4 = 49 million tons.

Texas extracted 1/7 th of the total = 1/7 * 49 = 7 million tons.
