Q 2 comp each produced 4800 utility bills in a day 1 comp bills at a rate of 9600 an hrn other at the rate of 7800 when 1 comp finished its run how many bills did the other comp still have to print?

• 900
  
  com 1 prints 9600 bills in 60 min
  => Time taken to print 4800 bills = (60/9600)*4800 = 30 min
  
  Therefore, in 30 min, comp 2 prints
  7800/2 = 3900 bills
  
  Bills remaining = 4800 - 3900 = 900 bills
