Answer:

businessman offers a series of discounts at 10%, 10% and 5%.

If the successive discounts d1, d2, and d3 are given on an item, then the selling price of that item is calculated by :

SP = (1-d1/100) (1-d2/100) (1-d3/100) × MP (Marked price)

Let the marked price of the item be 100 Rs.

SP = (1-10/100) (1-10/100) (1-5/100) × 100

= (1-0.1) (1-0.1) (1-0.05) × 100

= (0.9) (0.9) (0.95) × 100

= (0.81) (0.95) × 100

= 0.7695 × 100

= 76.95

Selling price would be 76.95 Rs.

Discount = 100 - 76.95 = 23.05 Rs.

Equivalent discount or Discount percentage = \frac{23.05}{100}\times 100

100

23.05

×100

= 23.05%

Equivalent discount of these three discount is 23.05%.
