The following bar graph shows the number of traffic violation fines (challans) issued in five different states during the month of March. Find the total number of challans issued in all 5 states combined for the month of March.

Given: Bihar = 560, Rajasthan = 680, Delhi = 880, Assam = 750, Jharkhand = 900 Formula used: Total = Sum of all values Calculations: ⇒ Total = 560 + 680 + 880 + 750 + 900 ⇒ = 1240 + 880 + 750 + 900 ⇒ = 2120 + 750 + 900 ⇒ = 2870 + 900 = 3770 ∴ The correct answer is 3770. Additional Information Data Interpretation Strategy Always list values clearly before adding to avoid missing any data. Addition Shortcut Group numbers into easy pairs (like 560 + 680) for faster calculation. Estimation Technique Round values to nearest hundred to quickly estimate total before exact calculation. Verification Tip Re-add using a different grouping method to confirm accuracy.
