Option 2 : 0.2 litres

**Given: **

A milkman has milk = 2400 ml

He received milk from milkman 1 = 7.2 L

He received milk from milkman 2 = 3500 ml

Pack volume = 300 ml

**Calculation:**

1 L = 1000 ml

2400 ml = 2.4 L

3500 ml = 3.5 L

300 ml = 0.3 L

Total milk with milkman = 2.4 + 7.2 + 3.5 = 13.1 L

Number of packs that can be made = 13.1 ÷ 0.3

∴ Number of packs can be made = 43

Quantity left = 13.1 - 43 × 0.3 = 13.1 - 12.9 = 0.2 L

**∴ After packing **0.2 L of **milk is left.**
