(A) 4 cups (B) 6 cups (C) 8 cups (D) 12 cups (E) 16 cups Flour:Water:Sugar = 7:4:1 Flour:Water = 7:4 New Ratio of Flour:Water = 14:4 = 7:2 (Multiplying the ratio by 2) Flour:Sugar = 7:1 New Ratio of Flour:Sugar = 7:2 (Halving the ratio) New Ratio of Flour:Water:Sugar = 7:2:2 For every 2 cups of water, there is 2 cups of sugar. IF you have 8 cups of water, you need 8 cups of sugar.

(A) 4 cups (B) 6 cups (C) 8 cups (D) 12 cups (E) 16 cups Hello, Flour/Water = 7/4, Flour/Sugar = 7/1 Double the ratio of Flour/Water = 7/4 * 2 = 7/2 Halve the ratio of Flour to Sugar = 7 * 1/2 = 7/2 The new ratio of Flour: Water: Sugar = 7:2:2 For 8 cups of water in the new recipe, sugar required will be 8 cups. Answer is C Hope this helps

I am not sure I follow you. Original Ratio of Flour:Water \(= 7:4 = \frac{7}{4}\) New Ratio of Flour:Water (original will be doubled) \(= \frac{7}{4}*2 = \frac{14}{4}\) Thereafter, I brought 14/4 to lowest terms 7/2. Original Ratio of Flour:Sugar \(= 7:1 = \frac{7}{1}\) New Ratio of Flour:Sugar (original will be halved) \(= \frac{7}{1*2} = \frac{7}{2}\)

Answer= B
Flour: Water:Sugar = 7:4:1
F:W is doubled so it becomes 14:4 And F:S is halved so it becomes 7:2 or 14:4
Thus new ratio is F:W:S = 14:4:4 or 7:2:2
That is, the ratio of water and sugar is same. So if there are 8 cups of water there should be 8 cups of sugar!

Initial: Flour(F):Water(W):Sugar(S)=7:4:1 Now, let's separate the ratios for convenience. F:W=7:4 ; F:S=7:1 Now, bring both ratios to the same denominator by multiplying, F:W=7:4 ; F:S=28:4 Now, quantity of F in F:W is doubled, F:W=14:4 Now, quantity of F in F:S is halved, F:S=14:4 Since the denominators are equal, we can write the new ratio together as, F:W:S=14:4:4 We see that water and sugar are both in equal quantities in the ratio. Hence, if we add 8 cups of water, we have to add 8 cups of sugar too. ANS. C

(A) 4 cups (B) 6 cups (C) 8 cups (D) 12 cups (E) 16 cups F:W:S = 7:4:1 F/W = 14/4(doubling ) W/F = 4/14 F/S = 7/2(halving )(multiply both numerator and denominator by 2) F/S = 14/4 Tally the ratios W:F:S = 4:14:4 So multiply the above ratio by 2 how much sugar is required => 8 cups

(A) 4 cups (B) 6 cups (C) 8 cups (D) 12 cups (E) 16 cups The original ratio is F : W : S = 7 : 4 : 1 Doubling the flour to water ratio gives us F: W = 14 : 4 = 7 : 2. Halving the flour to sugar ratio gives us F : S = 3.5 : 1 = 7 : 2. In the new recipe (or ratio), we see that water and sugar must be the same amount. Therefore, if the new recipe calls for 8 cups of water, we also need 8 cups of sugar. Answer: C
