Two successive price increase of 10% and 10% of an article are equivalent to a single price increase of
Let's say price of article is 100
After first increase its price will be 100(1+ $$\frac{10}{100}$$) = 110
Now second increment will be applied on 110

Which is 21 more than before any increment
Hence total percentage increment = 21
