Solution : Single discount of the two successive discounts of 15% and 20% = (15 + 20 – $\frac{15×20}{100}$)% = (35 – 3)% = 32% Now, the single discount of two successive discounts of 32% and 25% = (32 + 25 – $\frac{32×25}{100}$)% = (57 – 8)% = 49% Therefore, the successive discounts of 15%, 20% and 25% on an article are equivalent to the successive discounts of 49%. Hence, the correct answer is 49%.
