The marked price of a TV is Rs.16000. After two successive discounts, it is sold for Rs.11400. If the first discount is 5%, then the rate of second discount is

A) 15%
B) 20%
C) 30%
D) 25%

Correct Answer:




D) 25%

Description for Correct answer:
Let the rate of second discount = r%

Therefore, 11400 = \( \Large 16000\{ 1-\frac{5}{10} \left(1-\frac{r}{100}\right) \} \)

= \( \Large \frac{11400}{16000} \times = \frac{20}{19}=1-\frac{r}{100} \)

Therefore, r = \( \Large 100 \times \left(1-0.75\right) \) = 25%
