Question 2
In a certain year, California produced 2/7th and Texas produced 1/7th of all the Uranium ore produced in the United States. If all the other states combined produced 28 million tons that year, how many million tons did Texas produce 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 produced 2/7 + 1/7 = 3/7th of all the Uranium ore produced in the country.

Therefore, all the other states produced 1 - 3/7 = 4/7 th of all the Uranium ore produced 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 produced 1/7 th of the total = 1/7 * 49 = 7 million tons.
