Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFMales (M)+ female(F) = 18000
(105% of M) + (107% of F) = 19200.
Calculation:-
⇒ M + F = 18000 ...(1)
⇒ (105/100) M + (107/100)F = 19200 ...(2)
Put the value of M from equation (1) We get,
⇒ 105(18000 - F ) + 107F = 1920000
⇒ 2F = 30,000
⇒ F = 15,000
So,
⇒ M = 18000 - 15000 = 3000
The ratio of the populations of males and females = M / F
⇒ Ratio = 3000 /15000
⇒ Ratio = 1/5
∴ The required answer is 1/5.
