• Totally there are 900 second in 1/4th of an hour, similarly 4950 and 8400 seconds in 1 3/8 and 2 1/3 hrs respectively. so adding all...(900+4950+8400)/3600 = 9.958 hrs. so balance is (6-3.958 = 2.042 hrs)
  among the given options , option b) 2 hrs 2 1/2 mins has (7200+150 = 7350 seconds) = 7350/3600 = 2 hrs and 2 1/2 mins or 2.042 hrs. which is the right answer
