Question: Jill runs a business breeding llamas. Nine of her llamas got pregnant with 1 calf, and 5 of them got pregnant with twins. After they give birth, Jill traded 8 of the calves for 2 new adult llamas. Then she sells 1/3 of her herd at the market. How many total llamas (calves and adults) does Jill have now?
Answer: Step-by-step reasoning process: The number of calves that will be born as twins is 5 * 2 = 10 calves. The total number of adults and calves before the trade is 9 + 5 + 9 + 10 = 33. Jill had 33 - 8 = 25 left for trading 8 of the claves. But, she got 2 adult llamas in return, so she now has a total of 25 + 2 = 27 llamas. She then sold 27 / 3 = 9 llamas in the market. So, Jill has 27 - 9 = 18 llamas now.
So the answer is 18.

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.
Answer: 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.
So the answer is 84.

Question: Johnson has a sack of potatoes. He gives Gina 69 potatoes, gives Tom twice as much potatoes as he gave Gina and gives one-third of the amount of potatoes he gave Tom to Anne. How many potatoes does he have left if the sack contains 300 potatoes?
Answer: Step-by-step reasoning process: He gives twice 69 potatoes to Tom, which is 69 * 2 = 138 potatoes. He gives one - third of 138 potatoes to Anne, which is 138 * (1 / 3) = 46 potatoes. In total, he has given out 69 + 138 + 46 = 253 potatoes. He initially had 300 potatoes so he now has 300 - 253 = 47 potatoes left.
So the answer is 47.

Question: Ali and Sara ate 80 small apples combined. Ali ate 4 times more apples than Sara. How many apples did Sara eat?
Answer:
Step-by-step reasoning process: Let A be the number of apples Ali ate and S be the number of apples Sara ate. We have: A + S = 80 apples. And: A = 4S. Which means: 4S + S = 80. So: 5S = 80. So the number of apples Sara ate is: S = 80 / 5 = 16 apples.
So the answer is 16.
