Seven people, A, B, C, L, X, Y, and Z are sitting in a row, facing north. No one sits to the right of Y. Only three people sit between Y and C. Only two people sit between C and Z. B sits third to the left of X. L sits to the immediate right of X. How many people sit between A and Z?
Three
To solve the problem of determining how many people sit between A and Z, let's use the given constraints to arrange the people in sequence.
Step-by-step Arrangement:
- Y's Position: Since no one sits to the right of Y, Y is at the rightmost end of the row.
- C's Position: There are three people between Y and C. So, C must be fourth from the right.
- Z's Position: There are two people between C and Z. Therefore, Z is the leftmost person.
- X and B's Positions: B sits third to the left of X. L sits immediately to the right of X. This restricts X's position, making X third from the left and B sixth from the left.
- L's Position: L is immediately to the right of X, thus fourth from the left.
Given these arrangements, the setup from left to right is Z, A, B, X, L, C, Y.
Position Analysis:
Between A and Z, there are A and B. Therefore, there are three people sitting between A and Z.
Important Questions from Gravitation
Which of the following forces is responsible for the tides, due to the Moon and the Sun?
The weight of an object was 60 N when measured on the surface of the earth. What would be its weight when measured on the surface of the moon?
The universal constant of gravitation G has the unit
- An object's apparent weight is slightly less at the Earth's equator compared to its poles. This difference is primarily attributed to:
The gravitational force of attraction between two bodies is ‘F’ N. If each mass and distance between them is doubled, then the force of attraction between them is:
