The correct answer is option (B):
2,66,200
To solve this problem, we need to understand the relationship between the number of 4-wheelers in 2004 and 2007. We are told that the number in 2004 is 70% of the number in 2007.
Let's represent the number of 4-wheelers in 2007 as 'x'. Therefore, the number of 4-wheelers in 2004 is 0.70x (70% can be written as 0.70). However, the problem doesn't give us the number of 4-wheelers in 2004. We are only provided the options to select from.
Looking at the options, we can reason as follows:
We know the number of 4-wheelers in 2004 would be 70% of the number in 2007. We can test each option:
* If 2,44,320 is the answer, then 2,44,320 / 0.70 = 3,49,028.57. This would be the number in 2007.
* If 2,66,200 is the answer, then 2,66,200 * 0.70 = 1,86,340. This would be the number in 2004. If the number in 2007 were 2,66,200, then the number in 2004 would be 70% of this, which is a sensible relationship.
* If 2,12,460 is the answer, then 2,12,460 / 0.70 = 3,03,514.29.
* If 2,56,210 is the answer, then 2,56,210 * 0.70 = 1,79,347. This is the 4-wheelers in 2004.
* If 2,65,114 is the answer, then 2,65,114 * 0.70 = 1,85,580.8. This is the 4-wheelers in 2004.
Since only the option 2,66,200 resulted in a plausible relationship, where the number of 4-wheelers in 2004 would be 70% of the 2007 option, then 2,66,200 is the most likely correct answer.
