Study the following graph which gives the production (in hundreds) of scooters and motorbikes in a factory over the years and answer the questions.
The ratio of the number of scooter to that of motorbikes produced during the period 2000 to 2003 is
Number of scooters produced during the period 2000 to 2003 = 120 + 100 + 140 + 80 = 440
Number of motorbikes produced during the period 2000 to 2003 = 140 + 120 + 100 + 130 = 490
Required ratio = 440: 490 = 44: 49
