of the town is 2:5. The numbers of illiterate exceeds the number of literates by 9000
(Jabalpur, 2008) Ans. 21,000]​

Answer 1

Step-by-step explanation:

Let number of literate be 2x

Let number of illiterate be 5x

Since we know that the population of illiterates exceeds by 9000.

We can form an equation:

5x - 2x = 9000

3x = 9000

x = 9000/3

x = 3000

Now that we have got the value of x, we can find the number of literates and illiterates by substituting the value of x

2x = 2 x 3000 = 6000

5x = 5 x 3000 = 15000

Therefore, Total Population = Number of literates + Number of illiterates

= 6000 + 15000

= 21000

Hope it helps :D
