Answer:
the previous population was 62,000.
Step-by-step explanation:
The current population of a city = 83,700
The population of a city has increased by 35% since it was last measured.
We have to calculate the previous population before increasing 35%.
Let the previous population be p
p +(35% × p) = 83,700
p + 0.35p = 83,700
1.35p = 83,700
p =
p = 62,000
Therefore, the previous population was 62,000.

Let D be Daniel's present age, then we can represent Kevin's present age as 3D because Kevin is 3 times as old as Daniel.
We can write an expression for Daniel's age 4 years ago as D-4 and Kevin's age 4 years ago as 3D-4.
We are told that 4 years ago Kevin was 5 times as old as Daniel. We can write this information as:
Now let us solve our equation to find Daniel's present age.
![3D-4=5D-20](https://tex.z-dn.net/?f=3D-4%3D5D-20)
![-4+20=5D-3D](https://tex.z-dn.net/?f=-4%2B20%3D5D-3D)
![16=2D](https://tex.z-dn.net/?f=16%3D2D)
![D=\frac{16}{2}=8](https://tex.z-dn.net/?f=D%3D%5Cfrac%7B16%7D%7B2%7D%3D8)
Daniel's present age is 8 years. Now we will multiply 8 by 3 to get Kevin's present age as Kevin is 3 times old as Daniel.
![\text{Kevin's present age}=8\cdot3=24](https://tex.z-dn.net/?f=%5Ctext%7BKevin%27s%20present%20age%7D%3D8%5Ccdot3%3D24)
Therefore, Kevin is 24 years old now.
