Question

Answer 1

let me know if there is any problem

Answer 2

Solution :-

Let the female population of the town be x

Then, the male population will be (50000 - x)

Now, according to the question.

⇒ (50000 - x) × 105/100 + x × (103/100) = 52020

⇒ (5250000 - 105x)/100 + 103x/100 = 52020

⇒ 5250000 - 105x + 103x = 52020*100

⇒ - 2x = 5202000 - 5250000

⇒- 2x = - 48000

⇒ 2x = 48000

⇒ x = 48000/2

⇒ x = 24000 

So, female population was 24000

Male population was 50000 - 24000

= 26000
