two sofftware engineers each programmed 840 lines of code for a paarticular job.The first s/w engineer programmed 20 lines of code per minute.The second can do 11.5 lines of code.How many did the 2nd s/w engnr have left to do ?

• for 1st s/w engg.
  20 lines -> 1 min
  840 lines -> 840/20 = 42 min.
  
  for 2nd engg.
  1 min -> 11.5 lines
  42 min -> 42 * 11.5 = 483 lines.
  
  840 - 483 = 357 lines are left to do by 2nd engineer.
  
  ans is 357 lines
