A person sold a chair at a profit of 13%. Had he sold it for ₹607.50 more, he would have gained x%. If the cost price of the chair is ₹3750, then the value of x is:

29.2

Selling price = 13%.

If he sold it for Rs. 607.50 more, he would have gained x%.

CP of the chair = 3750

Profit percentage if profit is 607.50 = \(\frac{607.5}{3750}\) × 100 = 16.2%

Value of x = 13% + 16.2% = 29.2%
