Answer:

2400 people

Step-by-step explanation:

Let x be the number of people who had a swimming pool in the population of 10,000,

Thus, the ratio of people who had swimming pool to the total population = \frac{x}{10000}

Since, out of 250 people 60 had swimming pool,

So, the ratio of the people who had swimming pool to the total population = \frac{60}{250}

\because \frac{x}{10000}=\frac{60}{250}

\implies 250x=600000

\implies x=\frac{600000}{250}=2400

Hence, 2400 people in the city might one expect to have a swimming pool.

First option is correct.
