Answer 2

Answer: Cost of $6\dfrac{2}{5}$ liters of milk is $107\dfrac{1}{5}$

Step-by-step explanation:

Since we have given that

Cost price of milk per liter = $16\dfrac{3}{4}=\dfrac{67}{4}$

If quantity of milk = $6\dfrac{2}{5}=\dfrac{32}{5}\ liters$

Then, cost price of milk would be

= Each price × quantity of milk

=$\dfrac{32}{5}\times \dfrac{67}{4}\\\\=\dfrac{8\times 67}{5}\\\\=\dfrac{536}{5}\\\\=107\dfrac{1}{5}$

Hence, Cost of $6\dfrac{2}{5}$ liters of milk is $107\dfrac{1}{5}$
