Two successive discounts of 20% and 15% is equal to a net discount of .....

• let you have total amount of 100.
  then 15% of 100 =15
  therefore 100-15=85.
  then 20%of 85=17
  therefore net discount =15+17=32% ans.

• formula use with this type of problem == x+y-xy/100
  x=20,y=15
  net discount= 20+15-(20*15)/100
  =35-3=32%

• Let the total amount of 100.
  
  Then 20% of 100=20
  Now the amount is 80.
  Now 15% of 80=12
  The net discount =12+20=32....

• If x is printed price,
  final sp = x*0.8*0.85 = 0.68X
  discount = 0.32x
  Net % discount = 32%

• the discount at 20% is 0.2 . As it is discount deduct 0.2 from 1=>0.8 as price after first dicount. then, the second discount is 0.15*(0.8) and total will be 0.12
  so,price is 0.8-0.12=0.68
  total discount is =1-0.68=0.32

• simply we use a+b+(ab/100)
  as here we have discounts hence a=-20 & b=-15
  i.e -20-15+((-20*-15)/100)=-32% or a discount of 32%

• first add the two discounts i.e 20 + 15 = 35
  now subtract it with the product of the two divided by 100 i.e 35- (20 X 15)/ 100 = 32 ans.

• let sp=100
  Discount 100-20=80
  80*15/100=12
  80-12=68
  therefore total discount he gave 100-68=32(Ans)
