2) Population of Agra and Aligarh districts in the year 2001 was 36,20, 436 and 29,92,286, respectively. Estimate the total population of the two districts in that year to nearest ten thousand?

Answer 1

Answer:1)    Greatest no. - 3322

                     Smallest no. - 2233

                    We can make 6 numbers in all

Answer:2) 29,92,286 nearest ten thousand =  29,90,000

                  36 - 10,000

                  20 - 10,000

                  436 - 10,000

After Addition , the answer will be  30,20,000
