This simple arithmetic problem can be solved with the converse of the percentages given. Simple division.
suppose we have a number x and it is increased by 20% so the x becomes (100+20)x/100 = 120x/100, if it is decreased by 20% so the x becomes (100-20)x/100 = 80x/100. Please use this fundamentals to solve your problem
