Step 1: Find Chennai's 4 wheelers in 2002.
Table 2 gives Chennai's count in 2001 as 1.7 lakhs.
Table 1 gives the 2002 growth rate as 14%.
2002 count = 1.7 x (1 + 14/100) = 1.7 x 1.14 = 1.938 lakhs.
Step 2: Find Chennai's 4 wheelers in 2003.
The 2003 growth rate is 16%.
2003 count = 1.938 x (1 + 16/100) = 1.938 x 1.16 = 2.24808 lakhs.
Step 3: Convert to actual units.
2.24808 x 1,00,000 = 2,24,808.
Final Answer:
Chennai had 2,24,808 4 wheelers in 2003. \[ \boxed{2{,}24{,}808} \]
