Answer 1

Step-by-step explanation:

Let the population of Morgaon 2 years ago be 'x'.

Present population of this city =

$= x( {1 + \frac{10}{100} )}^{2}$

$= x( { \frac{100 + 10}{100}) }^{2}$

$= x \times \frac{110}{100} \times \frac{110}{100}$

$= \frac{121x}{100}$

According to the question,

$\frac{121x}{100} = 2420$

$= > 121x = 242000$

$= > x = \frac{242000}{121}$

$= > x = 2000$

Answer:- Population of Margaon city 2 years before is 2000.
