Question

who will answer the question I will mark as branliest​

Answer 1

Answer:

decrease percentage of 4%.

Step-by-step explanation:

let's suppose the number is 100

then 100+20% of 100

=100+20

=120

after this we are supposed to decrease it by 20%

so, 120-20% of 120

=120-24

=96

hence there will be a decrease percentage of 4%

Answer 2

Answer:

Decrease by 4%

Step-by-step explanation:

Its pretty simple,

say the number is 100,

so by 20% increase, it will be

100 + 100*20/100= 100 + 20 = 120

now, when its decreased by 20%,

120 - 120*20/100= 120 -24 = 96

so the number is decrease by 4 from the first number (i.e. 100)

Therefore, new decrease is 4% !
