Reasoning and answer: Half of Sid's original money is $48 / 2 = $24. Sid has only $24 + $4 = $28 left after his purchases. He had $28 + $8 = $36 before he spent $8 on snacks. So, Sid spent $48 - $36 = $12 on computer accessories.
The answer: 12

The number of girls in the classroom is 20 * 40% = 8 girls. Before new boys join, the number of boys in the classroom is 20 - 8 = 12 boys. If 5 new boys join, the new number of boys is 12 + 5 = 17 boys and the new total is 20 + 5 = 25 total people. The new percentage of girls in the class is 8 girls / 25 total people = 32%.
The answer: 32
Reverse engineering the question: A 20 person classroom is filled with 40% girls. If 5 new boys join the classroom, what is the new percentage of girls in the class?

Reasoning and answer: The adult pigs ate 3 / 5 * 300 = 180 straws. The total number of straws that the piglets shared is 300 - 180 = 120. Since there were 20 piglets, each piglet ate 120 / 20 = 6 straws.
The answer: 6
What was the question?
Question:
Troy had 300 straws. He fed 3/5 of the straws to the adult pigs and an equal number of straws to the piglets. If there were 20 piglets, how many straws did each piglet eat?
