Direction: Seven poles A, B, C, D, E, F and G are put in such a way that the distance between the next two decreases by 1 meter. The distance between the first two poles, A and B, is 10 meters. Now answer the following questions.
- 
					 What is the distance between the first pole A and the last pole G?
 
- 
                        
- 40 m
 - 49 m
 - 45 m
 - None of these
 - cannot be determine.
 
 
Correct Option: C
According to given above question, the distance and arrangement of Poles are ::
A_______10m_______B______9m______C_____8m_____D____7m____E___6m___F__5m__G.
Now calculate the distance between G and C Poles.
The distance between A and G 
= (10 + 9 + .... + 5)
