Answer 1

Answer:

65 is the answer

Step-by-step explanation:

simply form an equation and solve :-

(x - 25) * 5 = 200

(x-25) = 200/5

(x-25) = 40

x = 40+25

x = 65

Answer 2

Answer:

Let the original number be x

Given the number increased by 25%= x+0.25= 1.25x

Given the number decreased by 25%=1.25-0.25(1.25)

=0.9375.

%change = x- 0.9375/x * 100%

= 0.0625*100%

= 6.25

The decreased% is 6.25
