Let original price of potatoes be Rs. 100.
It increased by 10% then new price will be 100 + 10/100 × 100 = Rs. 110
Again it decreased by 8%.
Then price will be 110 - 8/100 × 110 = 110 - 8.8 = Rs. 101.2
Change in price = 110 - 101.2 = 8.8
percentage change in the price of potatoes  = 8.8/110 × 100 = 8%
