Question and rationale: The question is: An alien invades Earth. It abducts 200 people. He returns 80% of the people abducted. After that he takes 10 people to another planet. He took the rest to his home planet. How many people did he take to his home planet?
Step-by-step reasoning process: He returned 200 * .8 = 160 people. So he had 200 - 160 = 40 people. He took 10 of those to another planet so he took 40 - 10 = 30 to his home planet.

Question and rationale: The question is: Judy uses 10 pencils during her 5 day school week. A 30 pack of pencils costs $4. How much will she spend on pencils over 45 days?
Step-by-step reasoning process: She uses 2 pencils a day because 10 / 5 = 2. She will use 90 pencils in 45 days because 2 x 45 = 90. She will need 3 packs of pencils because 90 / 30 = 3. She will spend $12 because 3 x 4 = 12.

Question and rationale: The question is: Tom Brady is shy of the passing yards record in a season. The current record is 5999 yards. He currently has 4200 yards with 6 games left in the season. How many passing yards per game does he need to average to beat the record?
Step-by-step reasoning process: Tom needs to pass for 6000 - 4200 = 1800 yards to beat the record. Therefore, he needs to average 1800 yards / 6 games = 300 yards per game.

Question and rationale:
The question is: Lisa and Carly go shopping together. Lisa spends $40 on t-shirts then spends half of this amount on jeans and twice this amount on coats. Carly spends only a quarter as much as Lisa on t-shirts but spends 3 times as much on jeans and a quarter of the amount Lisa spent on coats. In dollars, how much did Lisa and Carly spend in total?
Step-by-step reasoning process: Lisa spends $40 on t - shirts / 2 = $20 on jeans. She also spends $40 on t - shirts * 2 = $80 on coats. So Lisa has spent a total of 40 + 20 + 80 = $140. Carly spends $40 / 4 = $10 on t - shirts. She also spends $20 per pair of jeans * 3 = $60 on jeans. She then also spends $80 Lisa’s cost for coats / 4 = $20 on coats. So Carly has spent a total of 10 + 60 + 20 = $90. Lisa and Carly have therefore spent a total of 140 + 90 = $230.
