  Liked some of those puzzles. 😨
  
  I want CEans to share really tough ones here.
  
  PS: Low response to this thread shows how hard time I had coming up with puzzles during the Grand Quiz Contest.

  Solve this:
  
  Data:
  A, B, C, and D want to get across a lake 312 miles across.
  Swimming speeds in mph: A=4, B=8, C=12, and D=16!
  They have a motorboat that goes at 48mph but this boat can only take 2 persons.
  D leaves first; 2 hours later the other 3 leave.
  During the last hour, a strong salmon decides to push the boat. This causes the boat to go 72mph during the last hour.
  All 4 arrive on other side at same time, 16 hours after D left.
  
  Questions:
  How many miles did the boat travel?
  For how many hours did A swim?
  How many miles did C swim?
  How many hours was B in the boat?
  
  NOTE: Everything is in complete miles and hours (no fractions of nothing), all speeds are constant, no interfering currents, no lost of time getting in/out of boat, no loss of time doing boat u-turns, no hanging on to the back of the boat or other such dishonest stuff; in other words, no dirty tricks to make your life miserable.

  Explanation:
  
  D left 1st....
  Hour no 1: D-16 miles
  Hour no 2: D-32 miles
  next A and B leave with the boat while C starts to swim..
  Hour no 3: D-48 miles, A-48 miles, B-48 miles, C-12 miles
  Hour no 4: D-64 miles, A-96 miles, B-96 miles, C-24 miles
  Hour no 5: D-80 miles, A-144 miles, B-144 miles, C-36 miles
  Hour no 6: D-96 miles, A-192 miles, B-192 miles, C-48 miles
  Hour no 7: D-112 miles, A-240 miles, B-240 miles, C-60 miles
  At this moment B leaves the boat, starts swimming and A comes back to take C....
  Hour no 8: D-128 miles, A-192 miles, B-248 miles, C-72 miles
  Hour no 9: D-144 miles, A-144 miles, B-256 miles, C-84 miles
  Hour no 10: D-160 miles, A-96 miles, B-264 miles, C-96 miles
  So, A meets C and C joins the boat....
  Hour no 11: D-176 miles, A-144 miles, B-272 miles, C-144 miles
  Hour no 12: D-192 miles, A-192 miles, B-280 miles, C-192 miles
  Hour no 13: D-208 miles, A-240 miles, B-288 miles, C-240 miles
  Hour no 14: D-224 miles, A-288 miles, B-296 miles, C-288 miles
  C leaves the boat, starts swimming and A comes back to take D....
  Hour no 15: D-240 miles, A-240 miles, B-304 miles, C-300 miles
  At the last hour, D joins the boat and boat travels with 72 miles/hr,
  Hour no 16: D-312 miles, A-312 miles, B-312 miles, C-312 miles.....
  
  All 4 reach at the same time..................
