Question
An electronic item is listed at Rs. 6000. After two
successive discounts, the final price paid is Rs. 4080. If the first discount is 15%, what is the percentage of the second discount?Solution
ATQ,
Let the second discount be x% According to the question, 6000 × 85% × (100 – x)% = 4080 ⇒ 5100 × (100 – x)/100 = 4080 ⇒ 51 × (100 – x) = 4080 ⇒ 100 – x = 4080 / 51 ⇒ 100 – x = 80 ⇒ x = 100 – 80 x = 20%
