1. From the given data in the question,
Decrease in city population = 25000 – 24500 = 500
Therefore, change in population = 500
Initial population = 25000
Percentage decrease = (Change in population / Initial population) × 100
On substituting the values, we get
= (500 / 25000) ×100
= 2%
2.
Increased in price of a car from Rs. 3,50,000 to Rs. 3,70,000
Amount change = Rs.3,70,000−Rs.3,50,000=Rs.20,000
Therefore, Increased percentage =
Amount of change/Original Amount × 100
[tex] \tt{ = \frac{20000}{350000} × 100} \\ [/tex]
[tex] \tt = {5 \frac{5}{7}\%.} \\ [/tex]
