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?

Let the initial price of one gram gold coin on Monday was 'P'.

According to the problem,

P$$\times\frac{90}{100}\times\frac{120}{100}\times\frac{108}{100}\times\frac{105}{100}$$ = 5511.24

P$$\times\frac{9}{10}\times\frac{12}{10}\times108\times\frac{21}{20}$$ = 551124

P$$\times\frac{9}{10}\times\frac{12}{10}\times27\times\frac{21}{5}$$ = 551124

P = 4500

The initial price of one gram gold coin on Monday was ₹4500.

Hence, the correct answer is Option C
