Dear Bipin
 
8 steps(F)- 6 steps(B) = 2 meters forward
2+ 8(F) -6 (B) = 4 meters forward
4+ 8(F) -6 (B) = 6 meters forward
6 + 8 (F) - 6 (B) = 8 meters forward
8 + 8 (F) - 6 (B) = 10 meters forward
10 + 8 (F) = 18 meters; fallen into a pit
Total steps = 78 steps
Hence after 78 seconds he will fall into a pit
