Question: During the hot dog eating contest, the 1st competitor ate 12 hot dogs in 3 minutes. The 2nd competitor ate twice that amount and the 3rd competitor ate 25% less than the 2nd competitor. How many hotdogs did the 3rd competitor eat?
Answer: Step-by-step reasoning process: The 2nd competitor ate twice the amount of the 1st competitor's 12 hot dogs So he ate 2 * 12 = 24 hot dogs. The 3rd competitor ate 25% less than the 2nd's 24 hot dogs, which is 24 / 4 = 6 hot dogs. If the 2nd competitor ate 24 hot dogs, and the 3rd ate 25% less than that, then the 3rd competitor ate 24 - 6 = 18 hot dogs.
So the answer is 18.

Question: Oliver owns a laundry shop, and he charges $2 per kilo of laundry. Two days ago, his shop washed a total of 5 kilos of laundries. Yesterday, it washed five kilos of laundries more than the previous day. Today, it washed twice the number of kilos than yesterday. How much did he earn for three days?
Answer: Step-by-step reasoning process: Yesterday, his shop washed 5 + 5 = 10 kilos of laundry. Today, it washed 2 x 10 = 20 kilos of laundry. Thus, Oliver's shop washed a total of 5 + 10 + 20 = 35 kilos of laundries for three days. Therefore, his shop earned 35 x $2 = $70 for three days.
So the answer is 70.

Question: Napoleon has 17 jelly beans and Sedrich has 4 more jelly beans than Napoleon. If twice the sum of Napoleon and Sedrich's jelly beans is 4 times the number of jelly beans that Mikey has, how many jelly beans does Mikey have?
Answer:
Step-by-step reasoning process: Sedrich has 17 + 4 = 21 jelly beans. The sum of Napoleon and Sedrich's jelly beans is 17 + 21 = 38 jelly beans. Twice the sum is 38 x 2 = 76 jelly beans. Mikey has 76 / 4 = 19 jelly beans.
So the answer is 19.
