Find a single discount equivalent to two successive discounts of 25% and 10%.

Correct option is C

Given:
Two successive discounts: 25% and 10%.
Formula Used:
Single Discount = $$1 - (1 - \frac {d_1}{100}) × (1 - \frac{d_2}{100}).$$​​
Solution:
Single Discount = 1 - $$(1 - \frac {25}{100}) × (1 - \frac{10}{100})$$​​
Single Discount= 1 - 0.75 × 0.90
Single Discount= 1 - 0.675
Single Discount = 0.325 = 32.5%
Answer: (c) 32.5%
