Answer:
75%
Step-by-step explanation:
we have
A ----> population of the city A
B ----> population of the city B
we know that
25% of B is equal to
[tex](25/100)B=0.25B[/tex]
so
[tex]A=B-0.25B[/tex]
[tex]A=0.75B[/tex]
[tex]0.75*100=75\%[/tex]
That means ----> population of city A is 75% of population city B
