The population of a city has decreased by 38% since it was last measured. If the current population is 27,900 .Previous population of city was 45000.
<u> Solution: </u>
Given that current population of city is 27900.
Also, population of a city has decreased by 38% since it was last measured.
Let assume that population of city when it was last measured = x
Decreased of 38% means x-38% of x . we can write this as,

Equating above expression to the given value of current population, we get
x=45000
Hence previous population of city was 45000.
