(8 marks
1,43,62,45,697. The total world population is 7,74,96,49,345. Is the population of
the world more than double the population of India and China combined?​

Answer 1

Answer:

India's population = around 1,00,00,00,000

China's population = around 1,00,00,00,000

1,00,00,00,000 + 1,00,00,00,000 = 2,00,00,00,000

2,00,00,00,000x2=4,00,00,00,000

total population = around 8,00,00,00,000

hence, it's false.
