Let the principal = ₹100

Rate = 20% per annum, compounded annually

Now calculate the amount over the years:

After 1 year: 100 × 1.20 = ₹120

After 2 years: 120 × 1.20 = ₹144

After 3 years: 144 × 1.20 = ₹172.80

After 4 years: 172.80 × 1.20 = ₹207.36

So, the amount just exceeds double (₹200) after 4 years.

Explanation

Let's calculate the population after 2 years:

Year 1:

Population = 50,000 + (4% of 50,000)

= 50,000 + 0.04 * 50,000

= 50,000 + 2,000

= 52,000

Year 2:

Population = 52,000 + (4% of 52,000)

= 52,000 + 0.04 * 52,000

= 52,000 + 2,080

= 54,080

The population after 2 years will be 54,080.
