# Find a Single Discount Equivalent to a Discount Series of 10%, 20% and 25%

**Answer: (3) 46%**

**Explanation:-
**The successive discount of 10% and 20% = 10 + 20 – 10 x 20/100

= 30 – 2

= 28 %

Then, the successive discount of 28% and 25% = 28 + 25 – 28 x 25/100

= 53 – 28/4

= 53 – 7

= 44%

Then, the successive discount of 10%, 20% and 25% is 46%.

Hence, the answer is (3) 46%.
