Given a fleet of 50 trucks, each with a full fuel tank and a range of 100 miles, how far can you deliver a payload? You can transfer the payload from truck to truck, and you can transfer fuel from truck to truck. Assume all the payload can fit in one truck.

• 50 trucks can cover a maximum of 100/50 + 100/49 + 100/48 + ...+100/2 +100/1 = 449.92 miles

• For Shweta ,
  50 trucks can cover a maximum of 100/50 + 100/49 + 100/48 + ...+100/2 +100/1 = 449.92 miles
  
  First of all , 50 trucks will cover a distance of 2 miles.
  All trucks are left with fuel which can take them to 98 miles further.
  From one truck, fill each of other 49 trucks with fuel reqd for 2 miles distance.
  so now one truck is empty ( without fuel and other 49 tank with full tank of 100 miles range).
  These 49 trucks will move further and cover 100/49 miles.
  All 49 trucks are left with fuel which can take them to 100-100/49 = 4800/49 miles further.
  From one truck, fill each of other 48 trucks with fuel reqd for 100/49 miles distance.
  so now one more truck is empty ( without fuel) and other 48 tank with full tank of 100 miles range).
  
  continue like this and you will get the desired result.
