This question is from an easy quations bin. The answer is number 5 as all other answers are either irrelevant or not supported by the argument

E sounds good to me.. C may not be the correct answer as it talks about wages only and doesn't talk about the cost to the store.

E is clear winner .
C is talking abt what "temporary service pays its auditors" which is irrelevant to the question asked.

Def. E. C is very tempting and I narrowed it down to C and E. But... If you notice C is already stated in the argument, thus it brings nothing new to the table.

E does so it must be E

Between C and E. The problem with C is that although it pays students 20% less money it is not sure if it wud be a feasible option. What abt the cost of training and teh insurance that are aforementioned in the passage. Hence answer is E.

I picked C because I thought that E is not necessarily true.

Example.)

1.) Cost of Temp Auditor=$100 2.) Cost of Student =$40
3.) Cost of Training = $30 4.) Cost of Insurance =$10

Total Cost of Student is $80 and Total cost of temp auditor is$100.

Now it is clear that training cost is \$30 which is more than 20% of the cost of temp auditor. So in this case E is not true.

Although C is not the best answer but I eliminated E for the above reason and went for C because it was the best answer to me.

Can somebody help me with my reasoning and explain why E is the answer?

E talks about training cost which could be high also. But C talks about holistic cost spent for students.

Good question , I really love this one

Cost of hiring outside auditors = 100
Cost of hiring college students auditors = 80

Other expenses = wages + training expenses +insurance
Other expenses = 80+ training expenses +insurance

Expenses for hiring college students auditors = college students auditors fees + Other expenses

Now , why option (E) -

Quote:
cost of training its own college student auditors is less than 20 percent of the cost of hiring auditors

It means ; Other expenses = 80+ ( training expenses +insurance )

( training expenses +insurance ) < 20 ( Ie. 20% of cost of hiring auditors )

This statement has to be true , if the cost of ( training expenses +insurance ) > 20 then the effective cost of hiring college students will be more than cost of hiring Auditors, hence will refute the original logic presented in the stimulus.

Hence IMHO (E) , errors in other options highlighted in RED.

PS : Please feel free to revert in case of any doubt , will love to explain further....
