The population of four cities in 2023 were recorded as follows: City A: 2,34,56,789; City B: 2,35,46,789; City C: 2,34,57,689; City D: 2,35,47,689. Which city has the largest population?
Options
City A
City B
City C
City D
Explanation
To compare large numbers, we start comparing digits from the leftmost place. All numbers have 8 digits.
- City A: 2,34,56,789
- City B: 2,35,46,789
- City C: 2,34,57,689
- City D: 2,35,47,689
All numbers start with '2' in the crores place. The next digit is '3' in the ten lakhs place for all. Now compare the 'lakhs' place (third digit from left): Cities A and C have '4', while Cities B and D have '5'. Therefore, Cities B and D are larger than A and C. Now, compare Cities B (2,35,46,789) and D (2,35,47,689). The 'ten thousands' place: City B has '4' and City D has '4'. The 'thousands' place: City B has '6' and City D has '7'. Since 7 is greater than 6, City D has the largest population.
