Answer:
The average salary of master's degree people is $ 63,000    And
The average salary of bachelor's degree people is $ 52,000   
Step-by-step explanation:
Given in question as :
Let the average salary of master's degree people = $ M       And
Let the average salary of bachelor's degree people = $ B
According to question , 
The average salary of master's degree people + The average salary of bachelor's degree people  = $115,000
Or , $ M + $ B = $ 115,000                                 ............. A
Again , 
$ M = 2 × $ B - $ 41,000                             ............... B
From eq A and eq B
(2 × $ B - $ 41,000 )   +  ( $ B ) = $ 115,000
Or, 3×$ B = 156,000
∴        B =  = $ 52,000
 = $ 52,000 
And   M = $ 115,000 - $ 52,000 
∴       M = $ 63,000 
Hence The average salary of master's degree people is $ 63,000    And
            The average salary of bachelor's degree people is $ 52,000   Answer
