Hint: In the given question consider the amount of one litre is Rs.100. Then convert the milk to water ratio (4:1) to gain a percentage ratio to find the total profit percentage easily. So, use this concept to reach the solution of the question.

Here ${\text{milk : water }} = 4:1$
${\text{milk : water }} = 100:25$
Therefore, total profit percentage $= 25 + 20 + \dfrac{{25 \times 20}}{{100}} = 25 + 20 + 5 = 50\%$
