"IT consultants must have extensive knowledge of their companies systems as well as great business and interpersonal skills. Because of this, interviews will feature questions about IT services themselves as well as case studies on how you would solve problems for clients purchasing those services. A bachelor's degree in IT, computer science, business, or a related field is required."
This question came up in the set venn diagram test. Out of 120 students, those with ID's that are even numbers are doing Physics, and all with ID's divisible by 5 are doing Chemistry, and all with ID's divisible by 7 are doing Maths. How many are doing Physics AND Maths? How many are doing Maths and Chemistry? How many are doing neither subject? etc..
Assuming the ID's range from 1-120: Number of students taking Physics: 60 (there are 60 numbers between 1-120 that are divisible by 2) Chemistry: 24 (only 24 numbers between 1-120 that are divisible by 5) Maths: 17 Physics and Chemistry: 12 Physics and Maths: 8 Chemistry and Maths: 2 All three subjects: 1
I got all the same expect Chemistry and Maths where i got the answer as 3. Could you please explain your working? Thanks
I got the same & also 3 (not 2)
