What is the single discount equivalent to the successive discounts of 20%, 35%, and 10%?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 53.2%.
The successive discount are 20%, 35% and 10%.
⇒ Net Discount = X + Y - (XY)/100 [Where,X = First discount, Y = Second discount]
According to the question -
⇒ First net discount = X + Y - (XY)/100 = 20 + 35 - 20(35)/100 = 55 - 7 = 48%
Now, again -
⇒ Single equivalent discount = 48 + 10 - 48(10)/100 = 58 - 4.8 = 53.2%
