A number of saplings are lying at a place by the side of a straight road. These are to be planted in a straight line at a distance interval of 10 m between two consecutive saplings. Mithilesh,the country's greatest forester,can carry only one sappling at a time and has to move back to the orginal point to get the next sapling. In this manner he covers a distance of 1.32 kms. How many saplings does he plant in the process if he ends at the starting point?Plz post a sol to this Q

1) 15
2) 14
3) 13
4) 12
5) 10

• distance travelled for 1st sampling 20 10 for going 10 for coming back
  2nd Sampling 40 till 12th he would have covered 220 add
  220+200+180+160+140+120+100...=1320 or 1.32km

• To plant the sampling the forester has to travel 20m,40m,....
  Total dist travelled=1.3km=1320m
  So,n=11.Here n is the number of terms in dist.
  no of samplings=11+1=12
