Question

A mixture contains 20% sugar, 5% salt, and the rest is flour. Find the quantity of flour in 2 pounds of this mixture.

• A. $\text{0.5 lb}$
• B. $\text{0.25 lb}$
• C. $\text{1.5 lb}$
• D. $\text{0.75 lb}$

Answer 1

The correct option is C $\text{1.5 lb}$

Percentage of sugar and salt $=20+5=25\%$
Percentage of flour $=100-25=75\%$
Quantity of flour in $2$ lb of the mixture $=\frac{75}{100}\times 2lb$
$=1.5lb$
