Quote:
A large manufacturing firm, on average, offers a higher compensation to skilled employees than to unskilled ones. This year, the management has decided to hire a higher number of skilled employees than they hired the previous year. This indicates that the average compensation of all the employees in the firm will increase this year.
Which of the following is an assumption on which the argument depends?
A. Skilled employees who received their training from abroad earn more than those who received such training domestically.
B. The higher average salary for skilled employees is not because of their scarcity in that firm.
C. The percentage of skilled employees is higher now than it had been the previous year in that firm.
D. The average salary of unskilled employees will not increase this year.
E. Employees who have advanced skillsets earn higher salaries than employees who don’t
GMATWhiz Explanation
Step 1 – Analysing the stimulus and question stemA large manufacturing firm, on average, offers a higher compensation to skilled employees than to unskilled ones.
• In a large manufacturing firm, skilled employees on average get paid more than the unskilled employees.
This year, the management has decided to hire a higher number of skilled employees than they hired the previous year.
• This year, a higher number of skilled employees will be taken by the firm than were taken in last year
This indicates that the average compensation of all the employees in the firm will increase this year.
• Conclusion: The average salary of all employees in the firm will rise.
Step 2 – Pre-thinking1. The passage tells us that the manufacturing company in general, offers higher salaries to skilled employees.
a. What if for some reason this year the company decides not to pay such higher salaries to skilled employees? Say earlier the company policy was to pay higher salaries to skilled employees. Now with more skilled employees being hired, what if their salary is lowered?
i. Assumption#1: The manufacturing firm will continue to pay similar higher compensation to the skilled employees this year too.
b. The passage talks about a higher number of skilled employees being hired. What if the number of unskilled employees hired this year is also significantly higher this year than last year? If that happens the proportion of skilled to unskilled employees may not increase and thus, the average salaries of all employees will also not increase.
i. For e.g-
1. Say last year there were 10 skilled and 20 unskilled employees. So the ratio was 1:2
2. Now this year say 40 skilled and 80 unskilled are hired. The ratio will still stay the same 1:2 and the average salaries will not increase.
3. So, it is necessary that the ratio of skilled to unskilled employees should increase this year after the hiring.
ii. Assumption#2: The ratio of skilled employees to unskilled employees will increase after the hiring of employees this year.
Step 3 – Answer Choice EliminationOption A AnalysisThis choice makes an irrelevant comparison between two kinds of skilled employees. The passage talks about skilled employees on average getting paid more. It is quite possible that some of the skilled employees get paid more than other skilled employees. The reason behind this salary difference is irrelevant to the discussion.
Incorrect Choice.
Option B AnalysisThis choice is more of a strengthener than an assumption. The fact that higher average salary for skilled employees is not because of their scarcity in that firm does make us believe that hiring more skilled employees will not affect their higher salary status. But this is not a must be true condition for the conclusion to be true.
Incorrect Choice
Option C AnalysisThis is in line with assumption#2.
Correct Choice.Option D AnalysisIf the average salary of all employees will increase then it means the average salary of unskilled employees will also rise. This choice implies just the opposite of what the argument conveys.
Incorrect Choice.
Option E AnalysisThis choice is similar to choice A. Who ears more because of what reason among the skilled employees is irrelevant to the discussion.
Incorrect Choice..
