[Question]While reading about the history of different towns, Jared learned that Euston had 20 more carriages than Norfolk. Norwich had 100 carriages, and Flying Scotsman had 20 more carriages than Norwich. If Euston had 130 carriages, how many carriages are there in all?
[Answer]If Flying Scotsman had 20 more carriages than Norwich, and Norwich had 100 carriages, then Flying Scotsman had 100 + 20 = 120 carriages. Together, Flying Scotsman and Norwich had 120 + 100 = 220 carriages. If Euston had 130 carriages, 20 more carriages than Norfolk, Norfolk had 130 - 20 = 110 carriages. Together, Euston and Norfolk had 110 + 130 = 240 carriages. Altogether, Euston, Norfolk, Norwich, and Flying Scotsman had 240 + 220 = 460 carriages. The answer is 460.
Q: Trevor's older brother was twice his age 20 years ago. How old was Trevor a decade ago if his brother is now 32 years old?
A: If Trevor's brother is 32 years old today then 20 years ago he was = 32 - 20 = 12 years old. If Trevor's brother was 12 years old and he was twice Trevor's age, then Trevor was 12 / 2 = 6 years old. If Trevor was 6 years old 20 years ago, then he must be 6 + 20 = 26 years old today. If Trevor is 26 years old today then a decade ago he must have been 26 - 10 = 16 years old. The answer is 16.
Question: One dandelion seed floated onto Mrs. Middleton's lawn, landed on good soil, and began to grow. After one month, the dandelion plant had grown to full size and developed a flower. At the end of the second month, the flower turned to 50 fluffy, white seeds, which blew onto the lawn. Only half of these seeds landed onto good soil, germinated, and began to grow, just as the first seed had done. If each of these new seedling plants produces the same number of seeds in the same amount of time as the original plant, what is the total number of seeds that these newest plants will produce in two months' time?
Answer: Half of the 50 seeds, or 50 / 2 = 25 seeds germinated and grew. If each of the 25 plants produces 50 seeds, then a total of 25 * 50 = 1250 seeds would be produced. The answer is 1250.
[Question]On Blacks, Martha goes to the mall to buy clothes on sale. For every 2 jackets she buys, she gets 1 free jacket. For every 3 t-shirts she buys, she gets 1 free t-shirt. Martha decides to buy 4 jackets and 9 t-shirts. How many clothes will she take home?
[Answer]For buying 4 jackets Martha gets 4 jackets / 2 = 2 jackets for free. For buying 9 t - shirts, Martha gets 9 t - shirts / 3 = 3 t - shirts for free. Adding the free jackets, Martha gets 4 jackets + 2 jackets = 6 jackets. Adding the free t - shirts, Martha gets 9 t - shirts + 3 t - shirts = 12 t - shirts. In total, Martha will take home 6 jackets + 12 t - shirts = 18 clothes. The answer is 18.
Q: With her savings, Sara bought two books: a book for 5.5£ and a book for 6.5£. She gives a 20£ bill to the seller. How much change does she get back?
A: To find out how much the saleswoman should return to her, we have to find out how much Sara spent in total. She spent 5.5£ + 6.5£ = 12£. So she gives 20£ and the cashier should keep 12£. The cashier therefore returns the difference between these two sums: 20£ – 12£ = 8£. The answer is 8.
Question: Arwen and Elrond picked some flowers. Arwen was able to get 20 tulips and Elrond was able to get twice as many tulips as Arwen did. How many tulips were they able to get in total?
Answer:
Elrond was able to get 20 x 2 = 40 tulips. Therefore, the total number of tulips they were able to get is 40 + 20 = 60. The answer is 60.
