a) Given that China's population is about 1.431 billion, we can express this number in terms of millions as well, since 1 billion equals 1000 million.
Therefore, the population of China in millions is:
1.431 billion * 1000 = 1431 million
So, the population of China is 1.431 billion or 1431 million.
b) In the Nepali numbering system, numbers are written quite similarly to the international system until the lakh mark (which is 100,000). Thereafter, the counting changes from the international million (10^6) to the Nepali crore (10^7). However, expressing numbers like 1.431 billion in words according to the Nepali system would be a manual task. The population in English words is "One billion four hundred thirty-one million." In the Nepali language, the equivalent would need to be translated manually.
c) To find the population of India, which is one crore fifteen lakh less than that of China, we first need to understand the numerical values of crore and lakh in terms of the international system. One crore equals 10 million (10^7), and one lakh equals one hundred thousand (10^5).
Add the values to find the difference:
One crore fifteen lakh is equivalent to:
1 crore = 10 million
15 lakh = 1.5 million
Total difference = 10 million + 1.5 million = 11.5 million
Now, we subtract this difference from the population of China to find the population of India:
Population of China = 1431 million
Difference = 11.5 million
Population of India = Population of China - Difference
Population of India = 1431 million - 11.5 million = 1419.5 million
Therefore, the population of India is approximately 1419.5 million, or 1.4195 billion when expressed in billions.
