A jar of black jelly beans has a ratio of 2:1, and 150 of the beans are black beans. How many beans in total are there in the jar?

This previous answer is incorrect, the correct answer is 225. This is because the black beans are twice as many as the other beans, which means the black beans are 150 and the other beans have to be 75. They want to know the TOTAL amount of jelly beans, which means you must add the two numbers together, which gives you an answer of 225!
