Answer:12 times
Step-by-step explanation:
Given
Population of city A is 2.6 \times 10^5
Population of city B is 1,560,000
Population of city C is twice of city B
thus Population of city C is [tex]2\times 1,560,000=3,120,000[/tex]
Thus Population of City C is [tex]\frac{3120000}{2.6\times 10^5}[/tex]=12 times of Population of city A
