Q: Ken can do 20 sit-ups without stopping. Nathan can do twice as many, and Bob can do half the number of Ken and Nathan's combined sit-ups. How many more sit-ups can Bob do compared to Ken?
A: Nathan can do 20 x 2 = 40 sit ups. Ken and Nathan's combined number is 20 + 40 = 60 sit - ups. Bob can do 60 / 2 = 30 sit - ups. Bob can do 30 - 20 = 10 more sit - ups than Ken. The answer is 10.

Q: Maria wants to paint a picture and needs some tools to do that. She wants to buy a set of brushes for $20 and some canvas for three times more than the brushes. The paint costs Maria $8 per liter, and she needs at least 5 liters. How much money will she earn on the painting if she will be able to sell it for $200?
A: Maria wants to pay 3 * 20 = $60 for the canvas. Maria needs 5 liters of paint, so the cost of it would be 8 * 5 = $40. So in total Maria will earn 200 - 40 - 60 - 20 = $80 if she will be able to sell the painting at the mentioned price. The answer is 80.
Question: Joseph had socks of many different colors. His dresser drawer was filled to overflowing with red, blue, black, and white socks. Uncertain of how many pairs he had of each color, he began to sort his socks. He discovered that he had three more pairs of blue socks than he had pairs of black socks. He had one less pair of red socks than he had pairs of white socks. He had twice as many blue socks as he had of red socks. And he counted a total of 6 red socks. What is the total number of Joseph's socks?
Answer: Starting with 6 red socks, twice the number of blue socks as red meant Joseph had 2 * 6 = 12 blue socks. With one less pair of red socks than white socks, this meant 2 fewer red socks than white, for a total of 6 - 2 = 4 white socks. Also, 12 blue socks = 6 pairs of blue socks. With three more pairs of blue socks than pairs of black socks, this means he had 6 - 3 = 3 pairs of black socks. And three pairs of black socks corresponds to 3 * 2 = 6 black socks. Thus, in total, he had 6 + 12 + 4 + 6 = 28 socks. The answer is 28.
