Answer:
So new price of per liter petrol is 96 p
Step-by-step explanation:
Given:
Price of Petrol = 80p
Increase in price = 20%
To find :
Cost per liter = ?
Solution:
As it is given that old price of petrol is 80p
Increase in price = 20 % of Old Price
New Price = Old price + Increase in price
Now first we will find increase in price
Increase in price = 20 % of 80
It could be written as
=[tex]\frac{20}{100}*80[/tex]
=[tex]\frac{1600}{100}[/tex]
Increase in price = 16 p
New price = old price + original price
= 80 p + 16 p
= 96 p
So new price of per liter petrol is 96 p
