Answer:
Let the number be 100
Increase in no. = 20% = (20/100 × 100
= 20) = 100 + 20 = 120
Decrease in resulting no. = (10/100 × 120) = 12
Therefore, decreased no.= 120 - 12 = 108
Overall % change = 108 - 100 = 8 %
(I have done this in a little long way, you can also just do it in a short way)
Increase in no. = 100 + 20 = 120
Decrease in resulting no. = 120 - 12 = 108
Overall % change = 108 - 100 = 8 %
(Hope it helps )
