Answer
Given, urban population of Punjab: 1,03,99,146
Urban population of Uttar Pradesh: 4,44,95,063
Urban population of Madhya Pradesh: 2,11,69,405
1. The urban population of Madhya Pradesh was :
The urban population of Madhya Pradesh is 2,11,69,405.
In the Indian system, 2,11,69,405 : Two crore eleven lakh sixty-nine thousand four hundred five.
Hence, option (c) is the correct option.
2. Difference = Population of Madhya Pradesh - Population of Punjab
= 2,11,69,405 - 1,03,99,146
= 1,07,70,259
Hence, option (b) is the correct option.
3. Total Population = Population of Punjab + Population of Uttar Pradesh + Population of Madhya Pradesh.
= 1,03,99,146 + 4,44,95,063 + 2,11,69,405
= 7,60,63,614
Hence, option (c) is the correct option.
4. The urban population of Uttar Pradesh is 4,44,95,063.
To round to the nearest lakh, we look at the digit in the ten thousands place, which is 9.
Since 9 is 5 or greater, we round up the lakhs digit. The lakhs part is 44, which becomes 45. The rest of the digits to the right become zeros.
Rounded population = 4,45,00,000
Hence, option (a) is the correct option.
