what will be single discount equivalent to three successive discounts of 50%, 30% and 20%?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 72%
Successive discount = a + b - ab/100
1st take 50 and 30
50 + 30 - 1500/100 = 65
Successive discount of 65 and 20 = 65 + 20 - 1300/100 = 85 - 13 = 72%
