Answer the following question.
Tatuya, Ivanna, and Dorothy took a quiz together. Tatuya scored twice as much as Ivanna, and Ivanna scored 3/5 times as many marks as Dorothy. If Dorothy scored 90 marks, calculate the average marks scored by the three.
Step-by-step reasoning process: Since Dorothy scored 90 marks, and Ivanna scored 3 / 5 times as many marks, Ivanna scored 3 / 5 * 90 = 54 marks. Together, Dorothy and Ivanna scored a total of 54 + 90 = 144 marks. If Tayuta scored twice as many marks as Ivanna, she scored 2 * 54 = 108 marks. The total marks the three scored altogether is 108 + 144 = 252 marks. The average marks for the three are 252 / 3 = 84 marks.
The answer is 84.

Answer the following question.
Johnny TV makes 25 percent more movies than L&J Productions each year. If L&J Productions produces 220 movies in a year, how many movies does the two production companies produce in five years combined?
Step-by-step reasoning process: Johnny TV makes 25 / 100 * 220 = 55 more movies than L&J Productions each year. The total number of movies that Johnny TV makes in a year is 220 + 55 = 275. Together, Johnny TV and L&J Productions make 275 + 220 = 495 movies in a year. In five years, the two companies make 495 * 5 = 2475 movies.
The answer is 2475.

Answer the following question.
On a 16 GB (gigabyte) capacity USB drive, 50% is already busy. Calculate the number of gigabytes still available.
Step-by-step reasoning process: We calculate 50% of 16 GB:. 50 / 100 * 16 GB = 0.5 * 16 GB = 8 GB. That leaves 16 GB - 8 GB = 8 GB available on this key.
The answer is 8.

Answer the following question.
Jess made 3 different stacks of wooden blocks. The first stack was 7 blocks high, the second stack was 5 block(s) higher than the first, and the final stack was 7 block(s) higher than the second. Jess’ little sister knocked over the entire first tower, in the second tower she left 2 blocks standing, and in the final tower she left 3 blocks standing. How many blocks in total fell down?
Step-by-step reasoning process: Jess’ second stack was 7 blocks + 5 blocks = 12 blocks. Jess’ third stack was 12 blocks + 7 blocks = 19 blocks high. Jess’ sister knocked down the second tower and knocked 12 blocks – 2 = 10 blocks knocked over. Jess’ sister knocked down the final tower and knocked 19 blocks – 3 = 16 blocks knocked over. Total blocks knocked over was 7 blocks + 10 + 16 = 33 blocks.
The answer is 33.
