The order of words changes from one batch to the next as follows: 1st word becomes 2nd, the 2nd becomes the last, the 3rd becomes the 1st * 4th remains the same, the 5th becomes the 6th * 6th becomes the 3rd and the last becomes the 5th
Dig -1; more -2; and -3; you -4; wilt-5; find -6; water -7
1st batch 9am to 10am 1 2 3 4 5 6 7 (4pm to 5pm)
2nd batch 10am to 11am 3 1 6 4 7 5 2 (5pm to 6pm)
3rd batch 11am to 12am 6 3 5 4 2 7 1 (6pm to 7pm)
4th batch 12:00 to 1pm 5 6 7 4 1 2 3 (7pm to 8pm)
5th batch 1pm to 2pm 7 5 2 4 3 1 6 (8pm to gpm)
6th batch 2pm to 3pm 2 7 1 4 6 3 5 (9pm to 10pm)
If the pass - code for third batch is 'any cold and at is hill station', it represents '6 3 5 4 2 7 1. As per the above arrangement pattern the code 'stations is cold at and any hill' will be 1 2 3 4 5 6 7' which represents the code for first batch.
