Price of a one gram gold coin decreased by 10% on its initial price on Monday and increased by 20% on Tuesday and again increased by 8% on Wednesday, and 5% increase on Thursday. If the final price on Thursday is ₹5511.24, then the initial price (in ₹) of one gram gold coin on Monday was?

4500

Let initial price = X

According to question ,

X × \(\frac{90}{100}\) × \(\frac{120}{100}\) × \(\frac{108}{100}\) × \(\frac{105}{100}\) = 5511.24

X × \(\frac{9}{10}\) × \(\frac{6}{5}\) × \(\frac{27}{25}\) × \(\frac{21}{20}\) = 5511.24

On solving ,

X = 4500
