Answer:

The original price is Rs. 50

Step-by-step 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:

  • Rs 500 per liter

Step-by-step 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
