There are four ships sailing on the sea of an infinite Watery planet with a plane surface. Assume that the ships are made of air And one can pass through another without disturbing its motion. Suppose The ships sail in straight lines and five of the six possible "collisions" are Known to happen. What else can you say about this situation?

50mangoes means 49gaps.1,3,5,7-----------------sum of all gaps gives distance to be walked=n/2[2a+(n-1)d]=49/2[2+48*2]=49*49=2401yards

for 50th mango he has to walk 49^2s=n/2(2*a+(n-1))for 2nd mangon=1for 3rd mangon=2for 50th mangon=49
