Step 1: Find Hyderabad's 4 wheelers in 2002.
Table 2 gives Hyderabad's count in 2001 as 1.6 lakhs.
Table 1 gives the 2002 growth rate as 12%.
2002 count = 1.6 x (1 + 12/100) = 1.6 x 1.12 = 1.792 lakhs.
Step 2: Find Hyderabad's 4 wheelers in 2003.
The 2003 growth rate is 13%.
2003 count = 1.792 x (1 + 13/100) = 1.792 x 1.13 = 2.02496 lakhs.
Step 3: Find the increase from 2002 to 2003.
Increase = 2.02496 minus 1.792 = 0.23296 lakhs.
Convert lakhs to units: 0.23296 x 1,00,000 = 23,296.
Final Answer:
Hyderabad had 23,296 more 4 wheelers in 2003 than in 2002. \[ \boxed{23{,}296} \]
