5 years ago, a mother was twice as old as her daughter. If the mother is 41 years old now, how old will the daughter be in 3 years?

The mother is 41 years old now, so 5 years ago she was 41-5=

<<41-5=36>>36 years old At that time the daughter's age was half hers so the daughter was 36/2=<<36/2=18>>18 years old Now (5 years after that time) the daughter is 18+5=23 years old In 3 years, the daughter will be 23+3=<<23+3=26>>26 years old #### 26 Krishna and Callum are playing a game where they earn 10 points if they win any round. If they played eight matches and Krishna won 3/4 of the matches, what is the total number of points that Callum earned? Krishna won 3/4 * 8 rounds = <<3/4*8=6>>6 rounds. If they played eight rounds, Callum won 8 rounds - 6 rounds = <<8-6=2>>2 rounds If a round earns one 10 points, Callum got 2 rounds * 10 points/round = <<2*10=20>>20 points. #### 20 Amanda had 7 candy bars. She gave 3 to her sister. The next day, Amanda won some prize money and bought another 30 candy bars. She gave her sister 4 times as many candy bars as she did the first time. How many candy bars did Amanda keep for herself altogether? Amanda has 7 - 3 = <<7-3=4>>4 candy bars. Amandy gives her sister 4 x 3 = <<4*3=12>>12 candy bars. She has 30 - 12 = <<30-12=18>>18 candy bars remaining. In total she keeps 18 + 4 = <<18+4=22>>22 candy bars. #### 22 James catches 3 kinds of fish. He catches 200 pounds of trout, 50% more pounds of salmon, and twice as much Tuna. How many pounds of fish did he catch? He caught 200*.55=100 pounds more salmon than trout So he caught 200+100=<<200+100=300>>300 pounds of salmon He caught 300*2=<<300*2=600>>600 pounds of tuna So in total, he caught 600+300+200=<<600+300+200=1100>>1100 pounds of fish #### 1100 John takes 3 days off of streaming per week. On the days he does stream, he streams for 4 hours at a time and makes $10 an hour. How much does he make a week? He streams for 7-3=<<7-3=4>>4 days a week So he streams 4*4=<<4*4=16>>16 hours a week That means he makes 16*10=$<<16*10=160>>160 a week #### 160 Angela has a collection of 24 pieces of rare action figures. She sold off a quarter of them at the pawnshop and gave one-third of the remainder to her daughter. How many does she have left? One-quarter of 24 action figures is 24*(1/4) = <<24*(1/4)=6>>6 She sold off 6 action figures so she has 24-6 = <<24-6=18>>18 left One-third of 18 is 18*(1/3) = <<18*(1/3)=6>>6 She gave out 6 so she has 18-6 = <<18-6=12>>12 left #### 12 There are 10 6-ounces of glasses that are only 4/5 full of water. How many ounces of water are needed to fill to the brim all those 10 glasses? A glass is filled with 6 x 4/5 = 24/5 ounces of water. So, 10 6-ounces of glasses contains a total of 24/5 x 10 = <<24/5*10=48>>48 ounces of water. To fill the 10 glasses to the brim, 10 x 6 = <<10*6=60>>60 ounces of water are needed. Hence, 60 - 48 = <<60-48=12>>12 ounces of water are still needed. #### 12 A desert garden’s sprinkler system runs twice a day during the cool morning and evening hours. It waters the garden with four liters of water in the morning and six liters in the evening. How many days does it take the sprinkler system to use 50 liters of water? Every day, the sprinkler uses 4 + 6 = <<4+6=10>>10 liters of water. Hence, it takes the sprinkler system 50 / 10 = <<50/10=5>>5 days to use 50 liters of water. #### 5 Bob is going to plant corn in part of his garden. The rows are 120 feet long, and each seed needs its own dedicated space of 18 inches to its right. How many seeds can Bob plant in each row? 18 inches is equal to 18/12 = <<18/12=1.5>>1.5 feet. Each row is 120 feet long, so there are 120/1.5 = <<120/1.5=80>>80 18-inch lengths on which seeds can be planted. #### 80 Annie spends 2 hours a week on chess club, 8 hours a week on drama club, and 3 hours a week on glee club. If there are 12 weeks in each semester and Annie takes the first two weeks off sick, how many hours of extracurriculars does she do before midterms? First find the total number of extracurricular hours Annie does per week: 2 hours/week + 8 hours/week + 3 hours/week = <<2+8+3=13>>13 hours/week Then find the number of weeks in a semester before midterms by dividing the total number of weeks by 2: 12 weeks/semester / 2 = <<12/2=6>>6 weeks/semester Then find the number of weeks before midterms that Annie wasn't sick: 6 weeks - 2 weeks = <<6-2=4>>4 weeks Then multiply Annie's weekly commitment by the number of weeks to find her total number of extracurricular hours: 13 hours/week * 4 weeks = <<13*4=52>>52 hours #### 52
