The stage starting at P5, ends at P3 and it is not the first stage (clue 4), and it is not the third stage (clue6). Hence the stage ending at P5 is not the fifth stage (the railway is circular). The stage ending at P5, is not the forth stage because that stage was awarded to Contractor (C) according to clue 7, whilst the forth stage was awarded to Contractor (D) according to clue 3. Neither the stage from P5 to P3, nor its precedent stage ending at P5, is the third stage since stage 3 ends at P1. Hence the stage ending at P5, is not the second stage and it must be the First stage, and the stage from P5 to P3 is the second stage.
Contractor (E) was awarded the contract for the stage starting at P4. This is not the First stage which was awarded to Contractor (C) according to clue 7 and the above analysis. It is not the second stage which starts at P5, and it is not the third which starts at P3, and it is not the forth stage which was awarded to contractor (D). Therefore Contractor (E) must have been awarded the fifth stage, starting at P4, and finishing at P2.
Stage 3 was not awarded to Contractor (A) according to clue 6. Contractor (A) was not awarded forth stage because it was awarded to Contractor (D), and he was not awarded stage 5 because it was awarded to Contractor (E), and he was not awarded stage 1 because that was taken by (C). Therefore Contractor (A) must have been awarded stage 2.
