Directions : A circular field with inner radius of 10 m and outer radius of 20 m is divided into 5 successive stage for ploughing. The ploughing at each stage, with starting points P1, P2, P3, P4 and P5 was is allotted to one of the five farmers F1,F2,F3,F4 and F5 not necessarily in that order.
• F5 was alloted the stage starting a point P4.
• The stage from P5 to P3 was not the first stage.
• F4 was allotted the work of the fourth stage.
• Finishing point of stage 3 was P1 and the work was not allotted to F1.
• F3 was allotted the work of stage ending at P5.
What are the starting and ending points of the field ploughed by F4?
Explanation
1. Identifying Key Constraints:
-
Stage 3 ends at P1. This implies Stage 4 must start at P1.
-
F4 was allotted Stage 4. Therefore, F4 starts at P1.
-
This immediately narrows our options to (a) or (b).
2. Determining the Point Sequence:
We have the points P1,P2,P3,P4, and P5. Let's look at the remaining clues to find the connections:
If we connect these logically in a circular flow:
3. Matching Stages to the Sequence:
-
If Stage 3 ends at P1, then according to the flow above, Stage 3 must be P3→P1.
-
If Stage 3 is P3→P1, then Stage 4 (the next stage) must be P1→P2.
-
Since F4 is assigned to Stage 4, F4 starts at P1 and ends at P2.
4. Verification:
-
Stage 5: P2→P4
-
Stage 1: P4→P5 (Starts at P4, which matches the clue for F5).
-
Stage 2: P5→P3 (Matches the clue "Stage from P5 to P3 was not the first stage").
This confirms the sequence is consistent with all the rules provided in the directions.
Answer:
The starting point for F4 is P1 and the ending point is P2.
Correct Option: (a) P1 and P2

3. Matching Stages to the Sequence:
-
If Stage 3 ends at P1, then according to the flow above, Stage 3 must be P3→P1.
-
If Stage 3 is P3→P1, then Stage 4 (the next stage) must be P1→P2.
-
Since F4 is assigned to Stage 4, F4 starts at P1 and ends at P2.
4. Verification:
-
Stage 5: P2→P4

Answer:
The starting point for F4 is P1 and the ending point is P2.
Correct Option: (a) P1 and P2
