The salt content in the solution is 32%. a) How many kilograms of salt are there in 75 kg of solution?

The salt content in the solution is 32%. a) How many kilograms of salt are there in 75 kg of solution? b) How many kilograms of solution should you take so that it contains 12.8 kg of salt? It was planned to pump out water from the basin in 30 days using 24 pumps. How many days will the work slow down if 6 pumps are out of order?

We know from the condition that the salt content in the solution is 32%. You need to find how many kilograms of salt are contained in 75 kg of solution. To find a solution, we will apply a proportion.

Let’s start by assuming 100% the weight of the entire solution. And the weight of salt, which is contained in 75 kg of solution, we denote using the variable x kg.

Now we can move on to composing the proportion:

75 kg of solution – 100%;

x kg of salt – 32%;

75 / x = 100/32;

x = (75 * 32) / 100 = 2400/100 = 24 kg of salt is needed to obtain a solution.
