Solution:
The milkman has to measure 5 litres of milk for the person but he has cans of 7 litres, 3 litres and 10 litres. So, he can measure 5 litres of milk by following the steps given below:
Step 1: Fill the 3-litre can with milk twice and pour the milk into the 10-litre can.
- Now, the 10-litre can has 6 litres of milk (3 litres + 3 litres = 6 litres).
Step 2: Fill the 7-litre can with milk from the 10-litre can.
- Now, the 10-litre can has 3 litres of milk and the 7-litre can has 7 litres of milk.
Step 3: Pour the milk from the 7-litre can into the person's container.
- Now, the 7-litre can has 0 litres of milk.
Step 4: Fill the 7-litre can with the remaining 3 litres of milk from the 10-litre can.
- Now, the 7-litre can has 3 litres of milk.
Step 5: Pour the milk from the 7-litre can into the person's container until it is full.
- Now, the person has 5 litres of milk in their container.
Therefore, the milkman can measure 5 litres of milk for the person by using the cans of 7 litres, 3 litres and 10 litres in the above-mentioned steps.
