Question

Find the Single discount in percentage which is equivalent to two successive discount of 45% and 40% given on an article​

Answer 1

Answer:

67%

Step-by-step explanation:

let any object price is  MP =  100

after first discount 45 percent  it become  cost price  = 55

and now 40 % discount it will cost 60% of 55 =  55 × 60/100 = 33

means if a object cost is 100 then after two successive discount of 45% and 40% is price become only = 33

so the over all discount can we calculated as

mP = 100

Cp = 33

discount = 67

so over all discount in % = (67/100)×100 = 67 %
