A garden contains 32 tomato plants. How many pepper plants does the garden contain?

(1) The ratio of the number of tomato plants to the number of pepper plants is 8 to 3.

(2) If the number of tomato plants is increased by 4, and the number of pepper plants stays the same, the ratio of the number of tomato plants to the number of pepper plants is

3 to 1.

To calculate the number of pepper plants, we need to know the ratio between them and the tomato plants or the total number of tomato+pepper plants.

We'll look for an answer that gives us this information, a Logical approach.

(1) This is precisely what we need.

Sufficient.

(2) This gives us the ratio between 32+4 tomato plants and the pepper plants.

Similarly to the above, this is also sufficient.

(D) is our answer.
