Question

the price of an article has been increased by 20% by how much percent the new price be reduced to retain its original price​

Answer 1

Step-by-step explanation:

let me take the number as 100.

so after 20% increment its price will be 120

then we take the percentage be x

then equation is

120 - 120×x÷100 =100

120 - 12x ÷ 10 = 100

120-100 = 12x÷10

20×10÷12 = x

x =16.67
