The marked price of a shirt is ₹2,150. Let two successive discounts offered by the store be 10% and ‘x%’. If the selling price of the shirt is ₹1,505, then calculate the value of ‘x’. [Give your answer correct to two decimal places.]

22.22%

Marked price = 2150

Selling price = 1505

First discount = 10%

Second discount = x%

Now SP after 10% discount = 90% of the marked price 

90% of 2150 = 1935

Final SP = 1505

Discount given = 1935 - 1505 = 430

Discount % = 430 × \(\frac{100}{1935}\) = 22.22%
