Question

If the sequence at a certain point is 5, E, 8, 7, 9 and it is known that component 2 is a larger component, which of the following MUST be true?

• A. Component 2 arrived before component 5.
• B. Component 2 arrived after component 7
• C. There is no larger component between components 5 and 8
• D. Component 9 is a smaller component.
• A. 2
• B. 3
• C. 4
• D. 5
• A. Component 5 is a larger component
• B. Component 5 left the belt between the two given sequences.
• C. Component 5 arrived after component 7.
• D. None of the above
• A. Component 7 is larger than component 4
• B. There was no component between components 4 and 6 in the first sequence.
• C. A larger component left the belt between the two sequences
• D. Component 5 is a smaller component
• A. 5
• B. 6
• C. 7
• D. Cannot be determined

Answer 1

The Correct Option is A

If component 2 is larger, it would occupy two spaces. Since component 5 is at the beginning of the sequence, there must have been a space before it, which could only be occupied by the second part of component 2.

Answer 2

Component 4 is larger, so it occupies two spaces. To accommodate components 6 and 9 after it, there must have been at least one empty space after component 4. This means components 1, 2, and 3 were present before component 4 arrived

Answer 3

In the first sequence, there's an empty space after component 5. In the second sequence, component 6 (a larger component) occupies this space. This is only possible if component 5 left the belt.

Answer 4

There's an empty space after component 6 in the first sequence but not in the second. To accommodate component 7, something (which must be a larger component) must have left the belt to create the necessary space

Answer 5

Maximum components would be achieved if every other component is a larger one. So, we can have a maximum of 3 larger components. With 4 empty spaces between them, we can fit in a maximum of 4 smaller components. Total: 3 larger + 4 smaller = 7 components
