The population of a town is 12000, if the number of males be increased by 6% and that of females by 8%, the population would be increased to 12800. Find the strength of females in the town.
Let's assume Males = x
Number of female = 12000 - x
As per the question,
x*(1.06) + (12000 - x)*(1.08) = 12800
x = 10,000
Females = 15000 - 10,000 => 5,000
