Answer:
Literate population = 6,000
illiterate population = 15,000
Total population = 21,000
Step-by-step explanation:
Literate population = 2x
illiterate population = 5x
No. of illiterate exceeds the literate by = 9,000
2x + 9,000 = 5x
9000 = 5x - 2x
3x = 9000
x = 9000/3
x = 3000
Literate population = 2x = 2 × 3000 = 6,000
illiterate population = 5x = 5 × 3000 = 15,000
Total population = 6,000 + 15,000 = 21,000
Check ⇒
No. of illiterate exceeds the literate by = 9,000
Difference between them should be 9000
15,000 - 6,000 = 9,000
9,000 = 9,000
L.H.S = R.H.S
