Correct Option: C
From the given bar diagram , we see
Total production of company X in the period 2002-2004 = 250 + 500 + 400 = 1150
Total production of company Y in the period 2002-2004 = 350 + 400 + 500 = 1250
Number of given years = 3
| Required ratio = |  | 250 + 500 + 400 |  | : | | 350 + 400 + 500 | | |||
| 3 | 3 |
Required ratio = 1150 : 1250 = 23 : 25
