B
32%
C
34%
D

Correct Answer: 32%
Let, the selling price be TK. 100. After 20% discount, selling price = 100 - 100 × 20% = 100 - 100 × 20100 = 100 - 20 = TK. 80Again, after 15% discount, selling price = 80 - 80 × 15% = 80 - 80 × 15100 = 80 - 12 = TK.68So, total discount = 100 - 68 = TK. 32 That means , total discount = 32%
