Given information:
- Population on 1 January 2001 = 1283575
- Growth rate in the last year = 10%
- Growth rate in the years prior to the last year = 5%
- In 1999, population declined by 20%

To find:
- Population on 1 January 1995

Approach:
We will calculate the population for each year from 1995 to 2001 using the given growth rates and population decline in 1999. Then, we will use the population of 2001 and work backward to find the population of 1995.

Calculation:
Let's start with the population in 2001, which is given as 1283575.

Year 2000:
- Growth rate = 5%
- Population in 2000 = Population in 1999 + Growth
- Population in 1999 = Population in 2000 / (1 + Growth rate)
- Population in 1999 = 1283575 / (1 + 5%) = 1220547
- But in 1999, there was a decline of 20%
- Population in 1999 = 1220547 - 20% of 1220547 = 976438

Year 1998:
- Growth rate = 5%
- Population in 1998 = Population in 1999 + Growth
- Population in 1998 = 976438 * (1 + 5%) = 1025610

Year 1997:
- Growth rate = 5%
- Population in 1997 = Population in 1998 + Growth
- Population in 1997 = 1025610 * (1 + 5%) = 1076891

Year 1996:
- Growth rate = 5%
- Population in 1996 = Population in 1997 + Growth
- Population in 1996 = 1076891 * (1 + 5%) = 1130735

Year 1995:
- Growth rate = 5%
- Population in 1995 = Population in 1996 + Growth
- Population in 1995 = 1130735 * (1 + 5%) = 1187272

Therefore, the population on 1 January 1995 was 1,200,000 (approx).

Hence, option (B) is the correct answer.
