Answer this question:The number of trees is three times more than the number of stones in the courtyard. There are also twice as many birds in the trees as the combined number of trees and stones in the yard. If the number of stones is 40, how many birds are in the trees?
The number of trees is three times more than the number of rocks, meaning there are 3 * 40 = 120 more trees than rocks in the courtyard. The total number of trees in the yard is 120 + 40 = 160. Combined, there are 160 + 40 = 200 trees and stones in the courtyard. Since the number of birds is twice the combined number of trees and stones in the courtyard, there are 2 * 200 = 400 birds on the trees.
The answer is 400.

Answer this question:Each year Dani gets 4 pairs of two pants each as pay winning the best Amazon buyer of the season. If he initially had 50 pants, calculate the number of pants he'll have in 5 years.
Since he receives four pairs of pants every year, and a pair has two pants, he gets 4 * 2 = 8 pants every year. After five years, the total number of pants he'll receive is 5 * 8 = 40 pants. If he initially had 50 pants, he'll have a total of 50 + 40 = 90 pants in five years.
The answer is 90.

Answer this question:A bicycle store is running a promotion. Every time a customer buys a bicycle, they will receive 2 bike clamps free with it. If the store sells 19 bikes in the morning and 27 bikes in the afternoon, how many bike clamps has the store given to customers?
In the morning, the store gives away 19 bikes * 2 bike clamps = 38 bike clamps. In the afternoon, they give away 27 bikes * 2 bike clamps = 54 bike clamps. So in total, the store has given away 38 + 54 = 92 bike clamps.
The answer is 92.

Answer this question:A fox can run at the maximum speed of 50 kilometers per hour. Considering the fox would run at a constant speed, what distance would he make during 120 minutes?
1 hour is 60 minutes, so 120 minutes is 120 / 60 = 2 hours. During one hour a fox can make 50 kilometers, so during two hours, he would be able to run 50 * 2 = 100 kilometers.
The answer is 100.
