Detailed Solution
Download Solution PDFLet the population of village A and Village B be A and B respectively.
⇒ A + B = 8250
⇒ 65B/100 + B = 8250
⇒ B = 5000
⇒ A = 3250
Let adults of village A and Village B be P and Q respectively while children of village A and Village B be S and T respectively.
⇒ P + S = 3250
⇒ 160S/100 + S = 3250
S = 1250 = children of village A
P = 2000 = adults of village A
⇒ Q + T = 5000
⇒ 1.5T + T = 5000
T = 2000 = children of village B
Q = 3000 = adults of village B
Required difference = 3000 – 2000 = 1000
