Correct Answer - Option 3 : 320 mL

**Given:**

The capacity of the bucket = 16 litres

Total number of times the mug is dipped = 50

**Formula used:**

The capacity of the bucket = n × Capacity of the mug

Here, n → number of times the mug is dipped

**Concept used:**

1 litre = 1000 millilitre

**Calculation:**

The capacity of the bucket = n × Capacity of the mug

⇒ 16 litre = 50 × Capacity of the mug

⇒ The capacity of the mug = (16 × 1000)/50 mL = 320 mL

**∴ The capacity of the mug is 320 mL**
