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.
