A. 30%

B. 28%

C. 26%

D. 25%

**Answer: Option B **

__Solution(By Examveda Team)__

Use Formula,Equivalent Discount = (A + B) - $$\frac{{{\text{AB}}}}{{100}}$$ where A = First Discount, B =Second Discount.

Equivalent Discount = (20 + 10) - $$\frac{{20 \times 10}}{{100}}$$

Equivalent Discount = 30 - 2 = 28%

**Graphic Change Method**

100 == 20%(disc.) ⇒ 80 == 10%(disc.) ⇒ 72

Equivalent discount = 28%
