Question

Sam filled 2$\frac{1}{3}$ liters of milk in a can in the morning. By evening 1$\frac{2}{3}$ liters of milk was left in the can. How much milk was sold during the day?

• A. $4$ liters
• B. $\frac{2}{3}$ liters
• C. $\frac{3}{2}$ liters

Answer 1

The correct option is B $\frac{2}{3}$ liters

Quantity of milk available in morning= 2$\frac{1}{3}$ liters
Quantity of milk available in evening
=1$\frac{2}{3}$ liters

Quantity of milk sold during whole day = Quantity of milk available in morning - Quantity of milk available in evening

$=2\frac{1}{3}$ liters $-1\frac{2}{3}$ liters

$=\frac{2\times 3+1}{3}-\frac{3\times 1+2}{3}$

$=\frac{7}{3}-\frac{5}{3}=\frac{7-5}{3}=\frac{2}{3}$liters

Quantity of milk sold during whole day is $\frac{2}{3}$liters.
