System Analyst worked 7½ hrs per day in one week.

He worked 37½ hrs from Mon - Fri.

He worked 4½ hrs more on Sat than he did on Sun.

He worked 2½ hrs on Sun.

How many hours did he work?

He worked 47 hrs.

You ought to show the working for this piece of fiction. Nowhere does the question say how many hours were worked on Saturday or Sunday.

I am assuming he worked 37½ in one week.

Assuming he worked 5½ each day from Monday to Friday, that's 27 work hours.

37½ - 27 = 10½

10½ - 4½ = 6

On Sunday he worked 6 hours and on Saturday he worked 10½ hours.

There's too much ambiguity in your question.

The question says he works37.5 hours on Monday through Friday. Also, if it was 5.5 hours per day, then Monday to Friday would be 27.5 not 27.

I am trying to guess what the original form of the question might have been.

He worked a total of 37½ hrs from Monday to Friday, (average 7½ per day)

He worked an extra 5½ hrs overtime on one week

He worked 4½ more hrs on Saturday than he did on Sunday

How many hours did he work all together ?

Let s be the number of hours he worked on Sunday

That means he worked s + 4½ hrs on Saturday

Total hours add up as 37½ + 4½ + 2s = 42 + 2s

If he worked say 2 hours on Sunday, total would be 42 + 4 = 46 hours.

This may not be quite what you meant, but it shows a method.

I like your logic; however, assuming he worked 5.5 hours of overtime over the weekend with 4.5 hours more on Saturday than Sunday, that would mean he worked 5 hours on Saturday and 0.5 hours on Sunday. Total for the week would be 42 hours.

Forget MATH, reading and reporting are NOT YOUR STRONG SKILLS, are they ??

Have you actually read your questions with its lack of punctuation? It makes no sense.

He "worked 5½ hrs in one week" and he "worked 37½ hrs from mon-fri". These two statements contradict each other unless he did negative work on Saturday and Sunday.

Let H be the hours worked on Sunday.

37.5 + (H + 4.5) + H = 5.5

So:

2H = 5.5 - 42 = -36.5

H = -18.25

He worked -18.25 hours on Sunday and -13.75 hours on Saturday. What was he doing? Destroying the work he had done between Monday to Friday?
