A milkman starts with a 100 liter can of pure milk from his dairy and he sells 10 liters of it to the first customer, then he adds 10 liters of water. After this, he sells 10 liters each to two customers and adds 20 liters of water. After this, he sells 10 liters each to three customers and adds 30 liters of water. Thus, every time he dilutes the mixture he sells it to one more customer than before and he keeps on replacing the mixture sold with water. In this way how many customers get at least 50% milk in the mixture that they purchase from this milkman

From a container of milk, which contains 200 liters of milk, the seller replaces each time with water when he sells 40 liters of milk(or mixture). Every time he sells out only 40 liters of milk(or mixture). After replacing the milk with water 4th time, the total amount of water in the mixture is

A dishonest milkman mixed 1 litre of water for every 3 litres of milk and thus made up 36 litres of milk. If he now adds 15 litres of milk to the mixture, find the ratio of milk and water in the new mixture.

When one litre of water is added to a mixture of milk and water, the new mixture contains 25% of milk. When one litre of milk is added to the new mixture, then the resulting mixture contains 40% milk. What is the percentage of milk in the original mixture?

A milk vendor has 2 cans of milk. The first contains 25% water and the rest milk. The second contains 50% water. How much milk should he mix from each of the containers so as to get 12 litres of milk such that the ratio of water to milk is 3 : 5?Options5 litres, 7 litres7 litres, 4 liters6 litres, 6 liters4 litres, 8 liters

A vessel has 400 litres of pure milk. 40 litres of milk is removed from the vessel and replaced by water. 40 litres of the mixture thus formed is replaced by water. This procedure is repeated once again. Find the percentage of milk in the resultant solution.
