**Answer: (3) 160000**

**Explanation:-**

The present population of city = 185220

The population of city increase at the rate of 5 % p.a.

Then, the population of a city one year ago = 185220 x 100/105

= 185220 x 20/21

= 176400

The population of a city two year ago = 176400 x 100/105

= 176400 x 20/ 21

= 168000

The population of a city three years ago = 168000 x 100/105

= 168000 x 20 / 21

= 160000

Then, the population of a city three years ago was 160000.

Hence, the answer is (3) 160000.
