The solution contains 14% salt. How many kilograms of solution do you need to take to get 49 kg of salt?

It is known from the condition that the solution contains 14% salt. In order to find how many kilograms of solution you need to take, in order to get 49 kg of salt, we will compose and decide the proportion.

Let’s take the weight of the solution as 100% and denote it using the variable x kg.

We make up the proportion.

x kg – 100%;

49 kg – 14%.

As a result, we get the proportion.

x / 49 = 100/14;

We need to find the unknown extreme term of the proportion.

x = (49 * 100) / 14 = 4900/14 = 350 kg of solution you need to take to get 49 kg of salt.

Answer: 350 kg of solution.
