Question

4. Find out the total population of a town if the ratio between the literate and the illiterate of
the inhabitants of the town is 2:5. The numbers of illiterate exceeds the number of literates
by 9,000.​

Answer 1

Answer:

21000 people

Step-by-step explanation:

the ratio of literates to illiterates = 2:5

let the constant of proportionality be x

so the numbers are 2x, 5x

illiterates exceed literates by 9000

5x-2x = 9000

3x =9000

x = 9000/3 = 3000

∴2x (literates) = 2 * 3000 = 6000

 5x (illiterates) = 5 * 3000 = 15000

so the total population = 15000 + 6000 = 21000
