Find the single discount equivalent to successive discounts of 25%, 20% and 10%.

To find the single equivalent discount for successive discounts of 25%, 20%, and 10%, we can calculate the final price after these discounts are applied sequentially to an initial value of 100.

Step-by-Step Calculation
Initial Value: Assume the marked price is 100.

First Discount (25%):

Discount = 25% of 100 = 25.

Remaining value = 100 - 25 = 75.

Second Discount (20%):

Discount = 20% of 75 = 15.

Remaining value = 75 - 15 = 60.

Third Discount (10%):

Discount = 10% of 60 = 6.

Remaining value = 60 - 6 = 54.

Final Equivalent Discount:

Total discount = Initial value - Final value = 100 - 54 = 46.

As a percentage, this is 46%.
