Explanation:
Numbers in the board
- Price of petrol in last year was Rs 45 per litre.
- New price of petrol after increament is Rs 50 per litre.
<h2>Have to find :-</h2>
<h3 /><h3>Concept :-</h3>
- 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
<h2>Solution :-</h2>
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%
<h3 /><h3>Hence :-</h3>
<h3>Let's Verify it</h3>
- 11.11 = 5/45 × 100
- 11.11 = 1/9 × 100
- 11.11 = 1 × 100/9
- 11.11 = 100/9
- 11.11 = 11.11
