In a building, there are a hundred ladies on the first-floor studying. There are three times that many girls at a party being held on the second floor of the building. How many ladies are on the two floors in total?

If there are a hundred ladies in the living room and three times that many girls at the party, there are 3*100=

<<3*100=300>>300 girls at the party. In the building there are 100+300=<<100+300=400>>400 ladies. #### 400 Chenny has 10 pieces of candies to be given out to her friends. She realized that she needs to buy 4 more so each of her friends will receive 2 candies. How many friends does Chenny have? Chenny has a total of 10 + 4 = <<10+4=14>>14 candies. If each friend will receive 2 candies each, then she has 14 / 2 = <<14/2=7>>7 friends. #### 7 Mona brought 20 cookies to share in class. Jasmine brought 5 fewer cookies than Mona. Rachel brought 10 more cookies than Jasmine. How many cookies altogether did Mona, Jasmine, and Rachel bring to share in class? Jasmine brought 20 - 5 = <<20-5=15>>15 cookies to class. Rachel brought 15 + 10 = <<15+10=25>>25 cookies to class. Mona, Jasmine, and Rachel brought 20 + 15 + 25 = <<20+15+25=60>>60 cookies. #### 60 There are 160 tissues inside a tissue box. If Tucker bought 3 boxes, and used 210 tissues while he was sick with the flu, how many tissues would he have left? When Tucker buys the tissue boxes, he has a total of 160 x 3 = <<160*3=480>>480 tissues. When he is sick with the flu and uses some of the tissues, he has 480 - 210 = <<480-210=270>>270 tissues left. #### 270 Jason has to drive home which is 120 miles away. If he drives at 60 miles per hour for 30 minutes, what speed does he have to average for the remainder of the drive to get there in exactly 1 hour 30 minutes? Jason drives 60 miles per hour * 0.5 hours = <<60*0.5=30>>30 miles initially He needs to drive an additional 120 miles total - 30 miles driven = <<120-30=90>>90 more miles He has 1.5 hours - 0.5 hours = <<1.5-0.5=1>>1 hour to drive the remaining distance He must average 90 miles per hour to drive the remaining 90 miles in 1 hour #### 90 Tim buys a book of esoteric words. He learns 10 words from it a day. In 2 years the book has increased the number of words he knows by 50%. How many words did he know originally? In 2 years there are 365*2=<<365*2=730>>730 days So he has learned 730*10=<<730*10=7300>>7300 words He knew 1/.5=2 times that number of words before the book So he knew 7300*2=<<7300*2=14600>>14600 words before #### 14600 The ratio of the amount of money Cara, Janet, and Jerry have is 4:5:6. If the total amount of money they have is $75, calculate the loss Cara and Janet will make if they combine their money to buy oranges and sell them at 80% of the buying price. The sum of the ratios representing the amount of money the three has is 4+5+6=<<4+5+6=15>>15 If the total amount of money they have is $75, the amount of money Cara has represented by the fraction 4/15 is 4/15*$75=$<<4/15*75=20>>20 Similarly, the amount of money Janet has represented by the fraction 5/15 of the total ratio is 5/15*$75=$<<5/15*75=25>>25 Combined, Cara and Janet have $20+25=$<<20+25=45>>45 If Cara and Janet buy goods worth $45 and sells them at 80% of the buying price, the selling price of the goods will be 80/100*$45=$<<45*80/100=36>>36 Since they bought the goods at $45 and sold them at $36, Janet and Cara would run at a loss of $45-$36=$<<45-36=9>>9 #### 9 Jack is making flower crowns out of red, pink and white daisies. There are nine times as many pink daisies as white daisies and three less than four times as many red daisies as pink daisies. If there are 6 white daisies, how many daisies are there total? First find the total number of pink daisies: 9 * 6 daisies = <<9*6=54>>54 daisies Then multiply that number by 4: 54 daisies * 4 = <<54*4=216>>216 daisies Then subtract 3 to find the total number of red daisies: 216 daisies - 3 daisies = <<216-3=213>>213 daisies Then add the number of each color of daisies to find the total number: 54 daisies + 213 daisies + 6 daisies = <<54+213+6=273>>273 daisies #### 273 The cost of a slice of cake is three-fourths of the cost of a cup of milk tea. If the milk tea costs $2.40, how much do 2 slices of cake and 1 cup of milk tea cost? The cost of a slice of cake is $2.40 x 3/4 = $<<2.4*3/4=1.80>>1.80. So, 2 slices of cake cost $1.80 x 2 = $<<2*1.80=3.60>>3.60. Therefore, 2 slices of cake and 1 cup of milk tea cost $3.60 + $2.40 = $6. #### 6 Milly is making feather boas for her dance team. Each flamingo has 20 tail feathers, and it's only safe to pluck 25% of their tail feathers at one time. If Milly needs to make 12 boas, and each boa has 200 feathers, how many flamingoes does she need to harvest? First find the number of feathers Milly can get from one flamingo: 20 feathers * 25% = <<20*25*.01=5>>5 feathers Then find how many feathers she needs total: 12 boas * 200 feathers/boa = <<12*200=2400>>2400 feathers Then divide the number of feathers she needs by the number of feathers per flamingo to find the number of flamingoes she needs to harvest: 2400 feathers / 5 feathers/flamingo = <<2400/5=480>>480 flamingoes #### 480
