A laptop is initially priced at ₹40,000. Its price is first increased by 15%. After that, a 12% discount is given. Following this, a festival discount of 8% is applied. Then, a warranty service charge of 5% is added, and finally GST at 20% is levied on the accumulated amount. What is the net percentage change in the final billed price compared to the original price of ₹40,000 (correct to two decimal places)?
