Total of blue, purple, and orange jellybeans is 14 + 26 + 40 = 80. There are 200 - 80 = 120 red jellybeans.
The answer: 120
Reverse engineering the question: A jar of jellybeans has 14 blue jellybeans, 26 purple jellybeans and 40 orange jellybeans. If there are 200 jellybeans in the jar, how many are there of the red color?

In six years, Jane will be 28 + 6 = 34 years old. Dara will be half the age of Jane in six years, meaning she will be 34 / 2 = 17 years old in six years. Currently, Dara is 17 - 6 = 11 years old. Dara has to wait for 25 - 11 = 14 more years to reach the company's minimum age of employment.
The answer: 14
Reverse engineering the question: The minimum age required to be employed at a company is 25 years. Dara aspires to work for the company and will be half the age of Jane in six years. If Jane is currently working for the company and is 28 years old, how long is it before Dara reaches the minimum age required by the company to be employed?

After the first mission, the number of cats remaining on the island was 1800 - 600 = 1200. If half of the remaining cats on the island were relocated to a rescue center inland, the number of cats taken by the wildlife service on the second mission is 1200 / 2 = 600 cats. The number of cats remaining on the island is 1200 - 600 = 600.
The answer: 600
Reverse engineering the question: After complaints from the residents of Tatoosh about the number of cats on the island, the wildlife service carried out a relocation mission that saw the number of cats on the island drastically reduced. On the first relocation mission, 600 cats were relocated from the island to a neighboring island. On the second mission, half of the remaining cats were relocated to a rescue center inland. If the number of cats originally on the island was 1800, how many cats remained on the island after the rescue mission?

He has 7 - 2 = 5 other classes. 7.5 hours - 1.5 hours = 6 hours. 6 hours = 360 minutes. 360 / 5 = 72 minutes. Keegan spends 72 minutes in one of his other classes.
The answer: 72
