This is the basic and conceptual question from Chapter name- Arithmetic Progression
Chapter number- 9
In this question we have been given that there are 25 trees at equal distances of 5 meter in a line with a well,
The distance of the well from the nearest tree being 10 meters.
A gardener waters all the trees separately starting from the well and he returns to the well after watering each tree to get water for the next.
Now we are asked to find the total distance the gardener will cover in order to water all the trees.
This is very important question.
