In the storage room of a certain bakery, the ratio of sugar to flour is 3 to 6, and the ratio of flour to baking soda is 5 to 1. If there were 30 more pounds of baking soda in the room, the ratio of flour to baking soda would be 4 to 1. How many pounds of sugar are stored in the room? Choose the correct choice from the following options:
A) 30
B) 50
C) 60
D) 45
E) 70
Sugar:Flour = 3:6 = 1:2 = 5:10   Flour:Soda = 5:1 = 10:2;   Thus we have that Sugar:Flour:Soda = 5x:10x:2x.   Also given that 10x/(2x+30) = 4/1 --&gt; x=60 --&gt; Sugar = 5x = 30.   30nswer: 30
