Consider the following information :
- Six books are kept one above the other
- History book is just above Commerce book and Mathematics book is just above Civics book and just below Physics book
- English book is between History and Civics books
Which book is between Mathematics book and English book ?
1. History (H) is just above Commerce (C): H C (block)
2. Mathematics (M) is just above Civics (V): M V (part of block)
3. Mathematics (M) is just below Physics (P): P M (part of block) -> P M V (block)
4. English (E) is between History (H) and Civics (V): H E V or V E H.
Combining the blocks and the ‘between’ rule:
If the order is V E H, and we connect it to the blocks:
P M V (P above M above V)
V E H (V above E above H)
H C (H above C)
Combining these results in the sequence: P, M, V, E, H, C from top to bottom.
Physics
Mathematics
Civics
English
History
Commerce
Let’s verify the rules with this order:
– Six books: Yes.
– History just above Commerce: Yes (H is just above C).
– Mathematics just above Civics: Yes (M is just above V).
– Mathematics just below Physics: Yes (M is just below P, P is just above M). So P M V block is correct.
– English between History and Civics: Yes (E is between V and H in the V E H sequence part of the full order).
The question asks which book is between Mathematics (M) and English (E). In the derived order P, M, V, E, H, C, the books are ordered vertically. Mathematics (M) is above Civics (V), and English (E) is below Civics (V). Therefore, Civics (V) is between Mathematics (M) and English (E).
