Question

the cost of an article is first increased by 30% and then decreased by 20% find the change percent​

Answer 1

increase in price is 20%

hence new price is 20% of 100 =20

so new price would be 100+20=120

. Afterwards,

there is a decrease of 30 % in price from 120 rs,

hence 30% of 120 is 36 so new price would be

120–36 = 84.
