answer it...​

Answer 1

The answer will be 200 ..........

the question carries the number population (2010) in form of 1.8×10⁶ so it can written like 18/10×1000000. Now the 10 below the 18 will be divided by 1000000 so it will remain 18×100000

=1800000

Now find the population of 2012

9×10³=9000

Now divide 1800000 from 9000

200 is your answer.

the solution of this question will be

population of 2010

1.8×10⁶

=1800000

the population of 2012

9×10³

9000

1800000/9000

200

So the the population of 2010 is 200 times more than 2012
