In a row, 25 trees are planted at equal distance from each other. The distance between Ist and 25th tree is 30 m. What is the distance between 3rd and 15th tree?
1) 8 m 2) 15 m 3) 16 m 4) 18 m

• Ans: (2) 15 m
  Solution: The distance between 1st and 25th tree gives 24 equal gaps.
  Given, 24 gaps = 30 m
  Therefore, 1 gap = 30/24 m = 5/4 m
  Thus, Distance between 3rd and 15th tree means 12 equal gaps, that is 12 * 5/4 = 15 m

• Let the distance between each tree = x m
  then total distance among 25 tree= (25-1)x=24x
  given,
  24x=30
  x=30/24=1.25
  hence the distance between each tree= x m =1.25 m
  so the distance between 3rd to 15th tree= (15-3)*1.25=15 m
  
  again
  distance

• 25-1=24,30/24=1.25. 15-3=12*1.25=15
