For next year, the Chefs’ Union has requested a 10 percent salary increase for each of its
members, whereas the Hotel Managers’ Union has requested only an 8 percent salary

Hi

Amongst the answer choices only option C talks about salary that 10% of x is higher than 8% of y since x>y C is correct option
Hope this helps.

a) The Chefs’ Union has many more members than does the Hotel Managers’ Union. - Number of members in each of the unions is irrelevant. Only their current income would help us determine or conclude something - Incorrect
b) The Chefs’ Union is a more powerful union than is the Hotel Managers’ Union and is therefore more likely to obtain the salary increases it requests. - Irrelevant and Incorrect
c) The current salaries of the members of the Chefs’ Union are, on average, higher than the current salaries of the members of the Hotel Managers’ Union. - Since the current average salary of all the chefs is higher than the Hotel managers avg salary, percentage increase in the salary directly alters the average be the same percentage. - Correct
d) The average dollar amount of the raises that the members of the Chefs’ Union received last year was equal to the average dollar amount of the raises that the members of the Hotel Managers’ Union received. - The premise talks about the salary increase for the current year rather than last year - Hence Incorrect
e) The members of the Chefs’ Union received salary increases of 10 percent in each of the last two years, while the members of the Hotel Managers’ Union received salary increases of only 8 percent in each of the last two years. - Data related to previous years is irrelevant in the current context - Incorrect

Experts plz pour in with some mathematical equations to solidify the method of doing such questions.

I have reached some equations , but unable to conclude.

conclusion:(TS/members)chef > (TS/members)Managers

where TS= total salary for particular category

Chef requested = 10%
Managers = 8%

So, what we need to know here

Q1. Number of members in each category?
Q2. base value of total salary?

Hello targetgmatchotu,

Note the words in bold in the passage "average dollar amount of the raises that the Chefs’ Union has requested for next year is greater than that of the raises requested by the Hotel Managers’ Union"

This sentence talks about the average salary raise which can be found by dividing the total raise in salary by the total number of chefs/managers. Hence, we do not need the total number of chefs and managers.

Hope this helps! Let me know in case I can help you any further.
