Question

To make bread dough, a baker mixes flour, eggs, yeast and salt by weight in pounds in the ratio of 11:9:3:2, respectively. how many pounds of yeast are required to make 20 pounds of bread dough?

Answer 1

$\text{Ratio of flour, eggs , yeast and salt in bread dough} = 11 : 9 : 3 : 2 \\ \text{let the quantity of flour, eggs , yeast and salt in the bread dough be} \: 11x, 9x, 3x and \: 2x \: \text{respectively} \\ \text{Total weight of dough} = 11x+ 9x+3x+2x = 25x\\ \text{ratio of yeast in mixture} = \frac{3x}{25x} \\ \text{Hence, quantity of yeast required to make 20 pounds of bread dough} = 20 \times \frac{3x}{25x} = 2.4 pounds$
