Thanks Murali, for the reply. I was searching for similar problems on Ratio DS- A came across another way of looking at this problem:

Stmnt1: From the question Stmnt 1 - we have a linear equation in one variable - Hence we can have a solution =>Sufficient

Stment2: From the question Stmnt 2- we have a linear equation in one variable - Hence we can have a solution =>Sufficient

Hence, the problem can be solved without doing any math.

Thanks,

Gary

A certain bread recipe calls for whole wheat flour, white flour, & oat flour in the ratio of 3:2:1, respectively. How many cups of oat flour are needed to make a loaf of bread?

1) A total of 30 cups of whole wheat and white flour are needed to make 3 loafs of bread.

2) Two more cups of whole wheat flour than white flour are needed for every loaf.

flours required (in # of cups) are in the ratio \(3:2:1\)

hence we can safely write the amounts (in # of cups) required as \(3x, 2x, x\)

Asked: what is x (i.e. the # of cups of oat flour required)

stmnt1:

30 cups for 3 loafs

==> 10 cups for 1 loaf

==> \(3x+2x = 10\)

==> \(x=2\)

Sufficient

stmnt2:

\(3x=2x+2\)

==>\(x=2\)

Sufficient

Answer D.

Murali.
