Question

One container is filled with a mixture that is 30% acid. A second container is filled with a mixture that is 50% acid.
The second container is 50% larger than the first, and the two containers are emptied into a third container. What
percent of acid is the third container?

Answer 1

Suppose the first container has 100 parts volume... It should have 30 parts of acid

The second container is fifty percent larger than the first... So its volume is 150 parts...50 percent of 150 is 75 which is the amount of acid

Hence the total amount in the third container is 30/100 + 75/150 = 120/150 that is 0.8 litres
