Consider first A & B cross the bridge. A returns with the torch.
Time taken is 2 + 1 = 3 minutesThen C & D cross the bridge. However, B returns with the torch.
Time taken is 8 + 2 = 10 minutes.Now, both A & B cross the bridge.
Time taken is 2 minutes.Total time taken: 3 + 10 + 2 = 15 minutes.

Start both the timers viz. 7min & 11 min.
When 7min timer completes, just reverse it so that it starts again..
When 11min completes, just reverse the 7min timer again (4 min would have lapsed = 11 – 7)
Wait for 7min timer to complete; it will take 4 min… totalling 11 + 4 = 15 minutes!

If M is the number of Men, then we have
C = 2M
W=2CPutting the above into equation, M + C + W = 35
M + 2M + 4M = 35.
Hence , Men = 5, Children = 10, Women = 20

For understanding this issue, lets consider 2 sides –> A & B. All are on side A.
First farmer takes chicken with him to side B.
Then he takes fox to side B
While returning to side A, he takes chicken with him (to side A)
Then he takes grain to side B
Finally, he takes the chicken to side B.This answer accepted by SherlockHolmes. on 13th February 2020 Earned 20 points.
