Question

Find the single equivalent discount of two successive discount 70% and 30%.​

Answer 1

Answer:

Let initial amount be 100

1> First discount is 70% then remaining price is 30

2>Second discount is 30% of remaining that is

30% of 30 which is 9

thus remaining is 30–9=21

Hence on 100 rs two successive discount of 70 and 30 lead to a price of 21

so total discount received = 100–21=79

Hence equivalent discount % = (79/100)*100=79%
