A number is increased by 10% and then decreased by 10%, the final value of the number is ? Choose the most appropriate option
A) decreases by 1%	B) decreases by 2%	C) decreases by 3%	D) decreases by 4%	E) none of the above
Here, x = 10 and y = - 10   Therefore, the net % change in value   = ( x + y + xy/100)%   = [10 - 10 + (10 * -10)/100]% or - 1%   Since the sign is negative, there is a decrease in value by 1%.   decreases by 1%NSWER:decreases by 1%
