Present population of town is 35,000 having males and
females. If The population of males is increased by 6%
and if the population of females is increased by 4%,
then after 1 year the population becomes 36,700.
Find the number males and females ?
Answer Posted / harish sharavan
at the beginning the population can be denoted as x+y=3500
After 1 year the population becomes x+(x*6/100)+y+(y*4/100)=36700
thus the 2nd equation is 1.06x+1.04y=36700 thus solving both equations we get x=15000,y=20000
Therefore the Final no. females =20800
&males is 15900
