Today, Malvika is prepared a dish that needed one and a half

Today, Malvika prepared a dish that needed one and a half bowl of noodles for 4 servings.
This means that today she made this dish in which 1.5 bowls were needed for 4 servings i.e. the recipe called for 1.5 bowls for 4 servings. What we don't know is how many servings she actually made today.
Hence 1 is not sufficient. We don't know the number of servings that she prepared today. So we can't say how many servings she will make on Saturday.

Today and earlier today are pretty much the same. Since they used past tense to show that she prepared this dish today (but some time ago) so they used the word 'earlier'

We can also check if our answer choice is correct from the statements given.

Suppose, from statement 1 we infer that Malvika prepared only four servings, looking at statement 2 we can immediately notice that it clashes with our inference from statement 1. Hence our inference should be wrong. To my knowledge, the statements never contradict each other.

Kudos Please... If my post helped.

The recipe is given, 1.5 bowl noodles for 4 servings not the amount she is going to make.
I hope you get it!

Answer is C

I have an issue with this answer as the serving size may or may not be same again. That needs to be stated for the answer to be C, else answer would be E.

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 time
Since we can answer the target question with certainty, the combined statements are SUFFICIENT

Answer = C

Cheers,
Brent
