[Question]Johnny is a guitar player and he has three colors of guitar picks: red, blue, and yellow. Half of his picks are red, one-third of the picks are blue, and the rest are yellow. If he has 12 blue picks, what is the total number of yellow picks in his collection?
[Answer]If one third (1 / 3) of his picks are blue, then 3 times the total number of blue picks equals his total pick count, or 3 * 12 = 36 picks. If half of the picks are red, then he has 36 / 2 = 18 red picks. If the rest of the picks are yellow, then he has 36 - 18 - 12 = 6 yellow picks. The answer is 6.
Q: On Black Friday a popular electronics store sells 327 televisions. This is 50 more than they sold last Black Friday. If this sales trend continues and they sell 50 more televisions each year for three years, how many televisions will they sell on Black Friday three years from now?
A: The electronics store sold 327 televisions this Black Friday and might sell 50 more televisions the next year, for a total of 327 + 50 = 377 televisions. The second year they might sell 377 + 50 = 427 televisions. The third year, if they continue to sell 50 more televisions than they did the previous year, they will sell 427 + 50 televisions = 477 televisions on the Black Friday three years from now. The answer is 477.
Question: John has 3 children. He and his wife are supposed to buy notebooks for their sons but they couldn't agree on how many to buy. So John bought 2 notebooks for each of his children and John's wife bought 5 notebooks for each of them. How many notebooks did they buy in total for their children?
Answer: John bought 2 notebooks for his 3 children: 2 notebooks / child x 3 children = 6 notebooks. The father bought 6 notebooks. John's wife bought 5 notebooks for their three children: 5 notebooks / child x 3 children = 15 notebooks. The mother bought 15 notebooks. Now, the total number of notebooks is 6 notebooks + 15 notebooks = 21 notebooks. The answer is 21.
[Question]In Dana's senior high school class there were 200 students. 60% of the students were female, and 50% of the females were brunettes. If 50% of the female brunettes were under 5 feet tall, then how many female brunettes in Dana's high school senior class were under 5 feet tall?
[Answer]In Dana's senior class, the 60% of 200 students is 0.6 * 200 = 120 female students. Fifty percent of the females, or 0.5 * 120 = 60 of the female students were brunettes. If 50% of the female brunettes were under 5 feet tall, then there were 60 * 0.5 = 30 female brunettes under five feet tall in Dana's senior class. The answer is 30.
Q: When Jeffrey walks, for every three steps forward, he takes two steps backwards. Therefore, if the distance between the house and the mailbox is 66 steps, what is the total number of steps Jeffrey takes when he goes from the house to the mailbox?
A: For every 3 steps forward, he adds 2 more backwards so each 'step' gained costs 5 actual steps. 66 steps distance * 5 steps moved = 330 steps total. The answer is 330.
Question: Lyla, a grocery store owner, bought rice weighing 30 kg less than green beans, which weigh 10 kg more than sugar. While carrying the goods to the store, the bags fell down and 1/3 weight of the rice and 1/5 weight of sugar was lost. If the green beans weighed 60 kgs, then how much did the remaining stock weigh?
Answer:
If rice weighed 30 kg less than the green beans, then the total rice weight is 60 kg - 30 kg = 30 kg. If the green beans weighed 10 kg more than sugar, then the total sugar weight is 60 kg - 10 kg = 50 kg. When 1 / 3 weight of rice was lost, the weight loss became 1 / 3 * 30 = 10kg. The weight of rice after the loss is 30 kg - 10 kg = 20 kg. When 1 / 5 weight of sugar was lost, the lost weight was 1 / 5 * 50 kg = 10 kg. The weight of sugar after the loss is 50 kg - 10 kg = 40 kg. The total weight for all the items is 40 kg + 20 kg + 60 kg = 120 kg. The answer is 120.
