Today, Malvika is prepared a dish that needed one and a half bowl of noodles for 4 servings. How many bowls of noodles will Malvika use next Saturday?
(1) Next Saturday, Malvika will make half the number of servings that she prepared earlier today.
(2) Earlier today, Malvika used half a dozen bowls of noodles to prepare her dish.
Target question: How many cups of pasta will Malik use the next time he prepares this dish? Given: 4 servings of a certain dish requires 1 1/2 cups of pasta. So, if we can determine the NUMBER OF DISH SERVINGS Malik prepares, we can determine how much pasta is required.
Statement 1: The next time he prepare this dish, Malik will make half as many servings as he did the last time he prepared the dish We have no idea how many servings Malik made last time. So, we cannot determine the number of servings he'll make next time.
So, statement 1 is NOT SUFFICIENT
Statement 2: Malik used 6 cups of pasta the last time he prepared this dish This information does not help us determine how much pasta he'll need NEXT TIME.
So, statement 2 is NOT SUFFICIENT
Statements 1 and 2 combined Statement 2: Malik used 6 cups of pasta the last time
Statement 1: Next time, Malik will make half as many servings as he did the last time. If we makes half as many servings, Malik will need half as much pasta as he needed last time.
So,
Malik will need 3 cups of pasta next timeSince we can answer the
target question with certainty, the combined statements are SUFFICIENT
Answer = C
