Question
Two successive discounts of 25% and 10% is equivalent to a
single discount of how much percentage?Solution
ATQ,
Let the marked price of an article be Rs. '100x'
Selling price after two successive discounts of 25% and 10% =100x × 0.75 × 0.90 = Rs. '67.5x'
So, equivalent single discount =
{(100x - 67.5x)/100x} = 32.5%
Alternate solution:
Required discount = 25 + 10 - (25 × 10)/100= 35 - 2.5 = 32.5%
