Eco Wildlife Preserve contains 5x zebras and 2x lions, where x is a positive integer. If the lions succeed in killing z of the zebras, is the new ratio of zebras to lions less than 2 to 1?

1) \(z > x\)
2) \(z = 4\)

No. of zebras left after z no. of zebras were killed = 5x – z;

New ratio of zebras and lions = (5x – z)/2x < 2/1

=> z < x.

Let's take each statement one by one.

1) \(z > x\)

Since z > x, the answer is no. Sufficient.

2) \(z = 4\)

Since we do not have any information about x, we cannot conclude whether z < x. Insufficient.

The correct answer: A

Hope this helps!
