Reasoning and answer: The price of the book is down by: 100 * 0.2 = $20. So the new price of the movie ticket is: 100 - 20 = $80.
The answer: 80

The hairstylist earns $5 x 5 = $25 for a normal haircut per day. He earns $6 x 3 = $18 for a special haircut. And he earns $8 x 2 = $16 for a trendy haircut. So, the total amount he earns per day is $25 + $18 + $16 = $59. Therefore, a hairstylist earns $59 x 7 = $413 per month.
The answer: 413
Reverse engineering the question: A hairstylist charges $5 for a normal haircut, $6 for a special haircut, and $8 for a trendy haircut. If he cuts 5 normal haircuts, 3 special haircuts, and 2 trendy haircuts per day, how much money does he earn per week?
Reasoning and answer: If the house has twice the number of large ones as medium ones then the house has 2 * 12 = 24 large ceiling lights. Similarly, if it has 10 more small ones than the 12 medium ones then it has 10 + 12 = 22 small ceiling lights. If one small ceiling light requires 1 bulb then 22 small ones will require 1 * 22 = 22 bulbs. If one medium ceiling light requires 2 bulbs then 12 medium ones will require 2 * 12 = 24 bulbs. If one large ceiling light requires 3 bulbs then 24 medium ones will require 3 * 24 = 72 bulbs. Therefore the house will require 22 bulbs for the small ones + 24 bulbs for the medium ones + 72 bulbs for the large ones, for a total of 22 + 24 + 72 = 118.
The answer: 118

20 * 13 = 260 square yards. 3 * 5 = 15 square yards. 260 - 15 = 245 square yards. Archie needs 245 square yards of sod.
The answer: 245
Reverse engineering the question: Archie needs to lay sod in his backyard that measures 20 yards by 13 yards. He has a shed on it that measures 3 yards by 5 yards. How many square yards of sod will Archie need for his backyard?

Question: Eduardo is a teacher. He taught 3 classes last week while his colleague Frankie taught double what Eduardo teaches. How many classes did Eduardo and Frankie teach in total?
Reasoning and answer: Day 1:50. Day 2:50(2) = 100. Day 3:100 + 20 = 120. Day 4:2(50 + 100 + 120) = 540. Total:50 + 100 + 120 + 540 = 810 eggs.
The answer: 810
