Question

# The present population of a town is 200000. Its population increases by 10% in the first year and 15% in the second year. Find the population of the town at the end of the two years.

Hint:

### Use the formula of total amount to find the total population at the end of 2 years.

## The correct answer is: 253000

### Complete step by step solution:

Present population of the town P = 200000,

We calculate the total population at the end of first year by the formula …(i)

Here, we have T = 1 years, P = 200000 ,R = 10% and A = ?

On substituting the known values in (i), we get

Hence total population at the end of first year = 220000

So the new population is 220000

Now the formula to find total population at the end of two years = …(ii)

Here, we have T = 1 years, P = 220000 , R = 15%(increases) and A = ?

On substituting the known values in (ii), we get

Hence total population at the end of second year = 253000
