Javier rates his work - readiness on a scale from 0 to 10, with 10 being maximum readiness. He wants his rating to be as high as possible when he arrives at his office and has found that the rating is being affected by how late he sleeps and how long he spends preparing for work. His alarm clock sounds at 6am, at which time he has a work - readiness of 10. He needs to leave for work at exactly 6:40am. During these 40mins, Javier's only activities are sleeping or preparing for work.
If Javier spends more than 25 mins or less than 10 mins to prepare, his rating is reduced by 5 points. To sleep past 6am, however, Javier must use the snooze button on his alarm clock, which delays the alarm by 4 mins. Each press of the snooze button after the third will decrease Javier's efficiency rating by 1 point.
In the following table, select for Rating the greatest work - readiness rating that Java can achieve and select for Snoozes the number of times he must press the snooze button to achieve that rating. Make only 2 selections, one in each column.

This is your typical conditions based TPA question. This thread already contains several responses with correct solution.
Watch this video solution and observe the sequence in which one should read the dataset and draw inferences in order to ‘own the dataset’ and efficiently solve this question. Here are some salient features:
Happy learning!
Watch this video solution and observe the sequence in which one should read the dataset and draw inferences in order to ‘own the dataset’ and efficiently solve this question. Here are some salient features:
- Observe how we read the conditions and observed that one condition for the loss of points is because of preparing and the second condition is because of snoozing.
- Notice how we drew the inference about the acceptable range of sleeping from the range of preparing that does not result in the loss of efficiency. Such sequencing of drawing inferences while you are reading the dataset is paramount to your comprehension of the dataset.
- And lastly, observe that we solved this ‘optimization’ problem even before we looked at the question stem. This is the output of reading the dataset with the intention of ‘owning the dataset’.
Happy learning!
