Question

in a state,there were 120 males for every 100 females.in the next census,the total population increases by 5% and the females increases by 10%.what was the percentage increase in male population?

Answer 1

Step-by-step explanation:it is given that for every 120 females there are 100 males which means males are 20% less than females

total population =100+120=220

if the census of total population increases by 5% then total population increases by 11 ,so total =231

females increase by 10% so female population is 132

let male population be x

accordingly we get

132+x=231

so x =99

hope this is helpful
