To determine how many more people live in China than in India, we need to subtract India's population from China's population. Given that China's population is approximately \( 1.45 \times 10^9 \) and India's population is approximately 1,400,000,000 (which is \( 1.4 \times 10^9 \)):
China's population: \( 1.45 \times 10^9 \)
India's population: \( 1.4 \times 10^9 \)
Subtracting the two gives us:
\( (1.45 \times 10^9) - (1.4 \times 10^9) = 0.05 \times 10^9 = 5 \times 10^7 \)
Therefore, there are \( 5 \times 10^7 \) (or 50 million) more people living in China than in India. The correct option is:
