A certain local newspaper has 80 employees. Of the employees, 3/5 are either journalists or copy editors. How many of the employees are journalists?

1) The newspaper employes more than 10 copy editors.
2) There are more than 3 times as many journalists at the paper as there are copy editors.

Say there are x no. of journalists and y no. of copy editors.

Thus, 3/5 of 80 = x + y

x + y = 48. We have to get the value of x.

Let's take each statement one by one.

1) The newspaper employes more than 10 copy editors.

y > 10. With this information, we can't get the unique value of x. Insufficient.

2) There are more than 3 times as many journalists at the paper as there are copy editors.

x > 3y. With this information, we can't get the unique value of x. Insufficient.

(1) and (2) together

Given y > 10, the minimum value of y = 11; thus, given x > 3y, the minimum value of x = 34. Since x + y = 34 + 11 = 45 < 48. x = 34 is a qualified value.

Let's take y = 12. At y = 12, the minimum value of x = 37. Since x + y = 37 + 12 = 49 > 48. x = 37 is NOT a qualified value.

Thus, x = 34. A unique value. Sufficient.

The correct answer: C

Hope this helps!
