- Let the price be 100
since series discount of 10% and 20%
10/100*100=10 (10 discount we get)
next discount of 20%
now price is 100-10=90
20/100*90=18 (18 discount we get)
so we get dis of 28 - 11 years agoHelpfull: Yes(5) No(0)
- To find overall discount equivalent to a series of discounts we use the formula
(x+y-(xy/100))
here x=10 and y = 20
overall discount = {10 + 20 - (10*20)/100 } = 30-2 = 28 % - 11 years agoHelpfull: Yes(3) No(0)
