Step-by-step explanation:
current population=120+100
=220
no of women=100
no of men's =120
total population increase by 25%
so that 220×25%
220×25÷100
55
no of persons increase is 55
no of women's increase in total population
100×20%
=20 women's
so that
no of men's will be =55-20
=35
therefore, percentage of total male's increase
=120+35×100÷220
=155×5÷11
=775÷11
=7.45%
