A dealer allows 32% discount on the marked price of an article and still gains 28%. If the cost price of the article is reduced by 10%, how much discount percent should the dealer allow now to get the same percentage of profit as before?
Show Hint
To calculate the new discount after a price change, use the relationship between the new cost price and the desired profit margin.
Let the cost price be \( C \) and the marked price be \( M \). The initial discount is 32% and profit is 28%. Use the profit and discount formula to find the new discount percentage when the cost price is reduced by 10%.
