The single discount is equivalent to a series discount of 60%, 70%, and 80%.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 97.6%.
Successive discount of 60% and 70% = 60 + 70 - (60 × 70)/100
= 60 + 70 - 42
= 88%
Successive discount of 88% and 80% = 88 + 80 - (88 × 80)/100
= 88 + 80 - 70.4
= 97.6%
Therefore, the equivalent single discount for 60%, 70%, and 80% is 97.6%.
