(1) The next time he prepares this dish, Malik will make half as many servings as he did the last time he prepared the dish.
(2) Malik used 6 cups of pasta the last time he prepared this dish.
3/2 cups of pasta are required for every 4 servings.
Statement 1:
Case 1: 8 servings made last time, 4 servings to be made next time
Since 3/2 cups are required for every 4 servings, the number of cups required for the 4 cups to be made next time = 3/2.
Case 2: 16 servings made last time, 8 servings to be made next time
Since 3/2 cups are required for every 4 servings, the number of cups required for the 8 cups to be made next time = 2(3/2) = 3.
Since the number of cups can be different values, INSUFFICIENT.
Statement 2:
Since the number of servings to be made next time is unknown, INSUFFICIENT.
Statements combined:
Since Malik used 6 cups of pasta last time -- and he will make 1/2 as many servings next time -- he will use 1/2 as much pasta next time, for a total of 3 cups.
SUFFICIENT.
The correct answer is
