Given that :-
- Price of petrol in last year was Rs 45 per litre.
- New price of petrol after increament is Rs 50 per litre.
Have to find :-
- Percentage increase
Concept :-
Here, at first we will assume the increase percentage as y Then, we will Subtract the new price by Old price and then we will use the formula [Increased amount/Original amount × 100 ]. Let's solve
Solution :-
Let the increased percentage be y
Increased Price = New Price - Old Price
Increased Price = 50 - 45
Increase in price = ₹5
Now,
y = [Increased amount/Original amount ] × 100
y = 5/45 × 100
y = 1/9 × 100
y = 1 × 100/9
y = 100/9
y = 11.11%
Hence :-
Let's Verify it
11.11 = 5/45 × 100
11.11 = 1/9 × 100
11.11 = 1 × 100/9
11.11 = 100/9
11.11 = 11.11
