Explanation:

1) A-B-S
[1/15 + 1/18 – 1/18] — 1/15 so this combination will fill tank in 15 minutes
2) B-C-P
[1/18 + 1/25 – 1/20] — 41/900 so this combination will fill tank in 900/41 = 21.9 minutes
Similarly
3) A-D-Q — 80/3 = 26.6 minutes
4) A-B-P — 180/13 = 13.8 minutes
5) B-D-R — 360/17 = 21.2 minutes

Hence, option 4 is the correct answer.
