In this question, the thing that needs to be found is the number whose 20% would be 18. The information's required for getting to the solution are already provided in the question. based on those given information's, the answer can be deduced very easily.
Let us assume the unknown number to be = x
Then
(20/100) * x = 18
x/5 = 18
x = 18 * 5
   = 90
so the unknown number in the question is 90. I hope the procedure is clear enough for you to understand.

We have a proportion: 18/?= 20/100

Cross multiply:
20*?= 18*100
⇒ ?= 18*100/20= 90

20% of 90 is 18~

s344n2d4d5 [400]

The population of the town in 36 years would be  8000.

<h3>What would be the population of the town in 36 years?</h3>

The formula that can be used to determine the town's population is:
FV = P (1 + r)^n

Where:

  • FV = Future value
  • P = Present value
  • R = rate of growth = 100%
  • N = number of years = 36/9 = 4

500 x 2^4 = 8000
