With step by step equation please​

Answer 1

Answer:

Price of a hairdryer with VAT = ₹ 5400

VAT% = 8%

Let the initial price of the hairdryer be ₹ x

Price of hairdryer with VAT is ₹ 5400

VAT % = 8%

VAT = 8% of the initial price of hairdryer

So, the initial price of hairdryer + VAT = 5400

x + 8% × x = 5400

x + (8x/100) = 5400

(108x/100) = 5400

x = 5400 × (100/108)

x = ₹ 5000
