Answers
Given : In a group of 80 employees, the number of employees who are engineers is twice that of the employees who are MBAs.
To find : How many employees are neither engineer nor MBA
Solution:
Total Employee = 80
Let say MBA = M
Engineer = 2M
The number of employees who are not engineers is 32
=> 80 - 2M = 32
=> 2M = 48
=> M = 24
Total = 80
MBA = 24
Engineer = 48
Let say employees who are both engineers and MBAs = B
Both = 2(MBA - Both)
=> B = 2(24 - B)
=> B = 48 - 2B
=> 3B = 48
=> B = 16
=> 16 employee are MBA & engineer Both
Total = MBA + Engineer - Both + None
=> 80 = 24 + 48 - 16 + None
=> None = 24
=> 24 are neither engineer nor MBA
24 are neither engineer nor MBA
