AI explanation

The equivalent cost price using the net discount formula or successive multiplication is 800 multiplied by 0.9 and 0.85, which equals 612. Adding 25 for transportation makes the total cost price 637. Selling the chair for 800 gives a gain of 163, and the gain percentage is 163 divided by 637 multiplied by 100, resulting in 25%.
