A mixture consists of flaxseed and cornmeal in the ratio 1 to 4, respectively. How many cups of flaxseed are used to make the mixture?
(1) There are a total of 15 cups in the mixture.
(2) The ratio of the number of cups of flaxseed to the total number of cups in the mixture is 1 to 5.
We are given the ration of flaxseed to cornmeal as 1 : 4 , hence from this we know that
1 cup of flaxseed for 5 cups of mixtures &
4 cups of cornmeal for 5 cups of mixture.(1) There are total 15 cups. Hence we can find flaxseed cups from this info - \(\frac{1}{5} * 15 = 3\)
Hence sufficient.(2) Ration of flaxseed to total is 1 : 5
No new info given here as we already know this from Q Not suffHence
Option (1) is correct.
Best,
