Step 1: Understand the Data
The problem provides:
1. Number of Rides (1980-1995): A bar graph showing rides in thousands (not explicitly labeled for 1981 and 1982).
2. Percentage of Total Rides (1982 and 1992): Pie charts showing the distribution among Maxi Cabs, Uber Cabs, Ola Cabs, and Others.

Step 2: Extract Key Information
Since the exact number of rides for 1981 and 1982 isn't provided numerically, we'll rely on the bar graph's visual estimation:
- 1981: Approximately $\(\mathbf{1 0 , 0 0 0}\)$ rides (from the bar graph).
- 1982: Approximately 14,000 rides (from the bar graph).

Step 3: Calculate the Percent Increase
Use the formula:

$$
\(\begin{aligned}
& \text { Percent Increase }=\left(\frac{\text { New Value }- \text { Old Value }}{\text { Old Value }}\right) \times 100 \% \\
& \text { Percent Increase }=\left(\frac{14,000-10,000}{10,000}\right) \times 100 \%=40 \%
\end{aligned}\)
$$


Step 4: Verify with Pie Chart Data (Optional)
The 1982 pie chart shows Maxi Cabs at $\(\mathbf{2 6 %}\)$, but this doesn't directly affect the total rides calculation. The bar graph is the primary source for total rides.

Conclusion
The approximate percent increase in rides from 1981 to 1982 is $\(40 %\)$.
