[Question]A building has 20 floors. Each floor is 3 meters high, except for the last two floors. The last two floors are each 0.5 meters higher. How tall is the building?
[Answer]There are 20 - 2 = 18 floors that are each 3 meters high. So the first 18 floors is 18 x 3 = 54 meters high. The last two floors are each 3 + 0.5 = 3.5 meters high. So the total height of the last two floors is 3.5 x 2 = 7 meters. Therefore, the building is 54 + 7 = 61 meters high. The answer is 61.
Q: Bob's school track is 400 meters. If Bob ran the first lap in 70 seconds, the second and third lap in 85 seconds each, what was his average speed in (m/s) for his entire run?
A: If each lap is 400 meters long, then 3 laps will have a total distance of 400 * 3 = 1200 meters. The total time he ran was 70 on the first lap + 85 on the second one and 85 on the third lap, so his total running time was = 70 + 85 + 85 = 240 seconds. His average speed then is measured by the total distance he ran (1200) divided by the total time required (240) or 1200 / 240 = 5 m / s. The answer is 5.
Question: Amaya scored 20 marks fewer in Maths than she scored in Arts. She also got 10 marks more in Social Studies than she got in Music. If she scored 70 in Music and scored 1/10 less in Maths, what's the total number of marks she scored in all the subjects?
Answer: The total marks Amaya scored more in Music than in Maths is 1 / 10 * 70 = 7 marks. So the total marks she scored in Maths is 70 - 7 = 63 marks. If she scored 20 marks fewer in Maths than in Arts, then he scored 63 + 20 = 83 in Arts. If she scored 10 marks more in Social Studies than in Music, then she scored 70 + 10 = 80 marks in Social Studies. The total number of marks for all the subjects is 70 + 63 + 83 + 80 = 296 marks. The answer is 296.
[Question]Mary has 300 sheep and Bob has double the number of sheep as Mary plus another 35. How many sheep must Mary buy to have 69 fewer sheep than Bob?
[Answer]Bob has (300 * 2) + 35 = 635 sheep. For Mary to have 69 sheep fewer than Bob she must own 635 – 69 = 566 sheep. As Mary has already 300 sheep she must buy 566 – 300 = 266 sheep. The answer is 266.
[Question]A large puzzle costs $15. A small puzzle and a large puzzle together cost $23. How much would you pay for 1 large and 3 small puzzles?
[Answer]
A small puzzle costs $23 - $15 = $8. Three small puzzles cost $8 x 3 = $24. So, 1 large and 3 small puzzles cost $24 + $15 = $39. The answer is 39.
