Initial price = ₹1 Per litre
current price = ₹52 Per litre
Change in price = current - initial = 52 - 1 = 51
there fore .. there is an increase of 51
percentage increase in price = (change/initial)×100
=(51/1)×100 = 5100%
current price = ₹52 Per litre
Change in price = current - initial = 52 - 1 = 51
there fore .. there is an increase of 51
percentage increase in price = (change/initial)×100
=(51/1)×100 = 5100%
