Answer 2

Answer:

Hello mate!!

Step-by-step explanation:

Let the total population be = x

20% increase in population = (20÷100)× x

Present population = x + (20÷100)× x

13800 = x + 2x÷10

13800 = (10x+2x)÷10

13800 = 12x÷100

x = 13800×(10÷12)

x = 11500

Therefore total population a year ago was 11500
