There was a population of 240 moose in a national park. after a year, the population increased by 25%.
how many moose are there in the park now?

Population of moose in the national park = 240
percentage increase in the population of moose in the national park after a year = 25%
Then
Amount of increase in the population
Of moose in the national park in a year = (25/100) * 240
                                                               = 240/4
                                                               = 60
So
The number of moose present after 1 year
in the national park = 240 + 60
                                = 300
So from the above deduction we can easily conclude that the number of moose in the national park after a year is 300.

Hi

Initial population = 100%
Final population = 100% + 25% = 125%

240 ⇒ 100% 
x ⇒ 125% 

100x = 125·240
100x = 30,000
x = (30,000)/100
x = 300 

The number of moose in National Park is 300

You would have to multiply all of the numbers
