Question

The price of petrol increased by 8% to Rs 540 per litre. Find the old price.​

Answer 1

The original price is Rs. 50

Explanation:

Let the original price be Rs.x

x+8% of x=54

x+(8/100)*x=54

x+8x/100=54

(100x+8x)/100=54

108x/100=54

x=54* 100/108

x=50.

The original price is Rs. 50

Answer 2

• Rs 500 per liter

Explanation:

Let the initial price be x.

We have:

• x + 8% of x = 540

Rewrite it as below and solve for x:

• x + 0.08x = 540
• 1.08x = 540
• x = 540/1.08
• x = 500
