Which ONE word is inappropriate?

Answer: Optimization

The words 'appraisal,' 'assessment,' and 'evaluation' are all synonyms that refer to the act of judging, estimating, or determining the value, quality, or significance of something. 'Optimization,' however, means to make something as effective, perfect, or functional as possible, describing a process of improvement rather than a judgment, making it the inappropriate word.

Henry, Arthur, and Peter each have one, three, and six novels, respectively. Henry is outnumbered by Arthur by 18 volumes. How many books total do the three have?

Answer: 90

Let the number of novels for Henry, Arthur, and Peter be 1x, 3x, and 6x respectively. The problem states Arthur outnumbers Henry by 18 volumes, so 3x - 1x = 18, which simplifies to 2x = 18, meaning x = 9. Therefore, Henry has 9 novels, Arthur has 27, and Peter has 54. Adding these together (9 + 27 + 54) gives a total of 90 novels.

At 4 p.m. on Wednesday, a clock accurately displayed the time. The time was off by 35 seconds the following Saturday at 2 o'clock. How many seconds did the clock jump every 30 minutes on average?

Answer: 1/4

First, calculate the total time elapsed: from Wednesday 4 p.m. to Saturday 2 p.m. is 70 hours (3 days and 22 hours). Convert this to minutes: 70 hours * 60 minutes/hour = 4200 minutes. The clock was off by 35 seconds over these 4200 minutes. To find the error per 30 minutes, calculate (35 seconds / 4200 minutes) * 30 minutes, which simplifies to 1050/4200, or 1/4 seconds.

John takes 30 minutes to wash a car. Joe is 20% slower than John at washing vehicles. How many cars can they wash in total if they work together for 2.5 hours?

Answer: 11

Explanation: John washes a car every 30 minutes, so in 2.5 hours (150 minutes) he can wash 150/30=5 cars Joe will wash 20% more cars in the same amount of time because he is 20% faster than John. This indicates that he will wash 20% more vehicles than John, or 5*(120%)=5*1.2=6 vehicles. In 2.5 hours, the two will wash 5+6=11 cars together. Advanced tip: It can be helpful to match up the units of the provided information in questions like these. Either make a change of 30 minutes to 0.5 hours or a change of 2.5 hours to 150 minutes. Advanced tip 2: If low on time, you can use this type of question to guess. You can look at the various replies and make an educated guess as to how many cars Joe washes rapidly (he'll wash 2 cars an hour, or 5 cars in 2.5 hours). Joe washes more quickly than Joe, therefore the two of them will wash more than five automobiles together, making 11 the only reasonable response.
