After two consecutive price increases of 10% for refrigerators in a shopping mall, the price has been increased by 5%. Now the original price is restored, and the price should be reduced by at least x%. What is x Our formula 1 (1 + 10%) (1 + 10%) (1 + 5%) (1-x%) = 1 The result is that 21% of them don't have this answer. The option is a 22 B 23 C 24 D 25

There is nothing wrong with the formula. The mistake lies in the choice of x value
1（1+10%）(1+10%) (1+5%)（1-x%）=1
1.2705x=0.2705
x=0.2705÷1.2705
X=0.2129=21.29%
Because the price should be reduced by at least x%, and when x = 21%, the original price will not be restored
So take 22 according to option X
