Answer»

GIVEN,

Ratio of Populations of villages X and Y = X ? Y = 34 ? 43

Ratio of Populations of villages X and Y if the population of village Y INCREASE by 125000 = X ? (Y + 125000) = 17 ? 24

X ? Y = 34 ? 43

⇒ X/Y = 34/43

⇒ Y = 43X/34

Now,

X ? (Y + 125000) = 17 ? 24

⇒ X/ (Y + 125000) = 17/24

⇒ X/ (43X/34 + 125000) = 17/24

24X = 43X/2 + 2125000

⇒ X = 850000

The population of village Y = 43 × 850000/34 = 1075000

∴ The population of village Y = 1075000
